Description: APPLIANCES WITH MULTIPLE MODES OF OPERATION CROSS REFERENCE TO A RELATED APPLICATION This application is related to copending provisional application No. 60/1 15,197. The benefit of the filing date of that application is hereby claimed. TECHNICAL FIELD OF THE INVENTION The present invention relates to novel appliances with multiple modes of operation. BACKGROUND OF THE INVENTION Heretofore invented have been certain new and novel appliances with multiple, user-selectable operating modes. The appliances are capable of carrying out different ones of multiple functions. A function is called up by choosing the appropriate, user-selectable mode. Examples of the operating modes which different ones of the subject appliances have and the function of the appliance in each of these modes appear below. Mode Function TELEVISION Allows the user to watch television CD Allows the user to play a conventional audio (on audio/visual) disk; in this mode the user can also play a disk of the character described in U.S. patents Nos. 5,724,102 and 5,801 ,784 to retrieve lessons on a particular subject or information on performing a task from the disk. APPLIANCE Gives the inte g rated module control over one or more appliances — as examples only, a kitchen range, refrigerator, central heating system, air conditioner, or central vacuuming system. Also, diagnostic information on the controlled appliance(s) may be gathered and made available on the display screen of the appliance and at a service or repair facility. Appliances of the character described above with Internet capabilities are disclosed in copending U.S. patent application No. 09/046,947. In the INTERNET mode of operations a user can log onto and browse the Internet and send and receive e-mail messages. SUMMARY OF THE INVENTION Disclosed herein are certain new and novel appliances which have all five of the operating modes identified above. One or modes may be disabled to best fulfill the requirements of a particular market or other purposes. In the INTERNET mode of operation, commands can be inputted to a integrated unit component of the module from a keyboard as well as from a remote control or onboard controls of the appliances disclosed herein. This has a number of advantages. For example, an e-mail message can be composed by typing characters on the keyboard instead of selecting the characters with an arrow and then clicking on the character, the approach employed in using a remote control as disclosed in the '947 application. Another feature of the novel appliances disclosed herein is that links appearing on a web site page such as those disclosed in the '947 application can be selected by activating a remote control button or a number key on a keyboard. This simplifies Internet browsing which, in the appliances disclosed in the '947 application, require the user to move a cursor to the related link and click on the link. Yet another significant advantage of the appliances disclosed herein is that transitions from one operating mode to another can be made almost instantaneously. This eliminates the distraction and frustration which a slower transition would cause. Still another advantage of the appliance disclosed herein is that a user is returned to the point where operation in a mode is when the user exits from and then returns to a mode. This is particularly advantageous when the user would otherwise have to perform a number of steps to return to the first mode. The objects, advantages, and important features of the present invention will be apparent to the reader from the foregoing and the appended claims and as the ensuing detailed description and discussion proceeds in conjunction with the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a pictorial view showing the components of an appliance (or system) which has the capacity of operating in a user-selected one of plural operating modes and which is constructed in accord with, and embodies, the principles of the present invention: FIG. 2 shows, diagrammatically, the inputs to which a video monitor and speakers of the FIG. 1 appliance are switched when different ones of the available operating modes are selected; FIG. 3 shows the relationship between FIGS. 3A and 3B which, taken together and with FIG. 2, schematically depict the operating components of an integrated unit which is an element of the FIG. 1 appliance; this figure also shows other elements of the appliance as well as certain inputs to and elements controlled by the operating components of the integrated unit; FIG. 4 is a plan view of the remote control; shown in FIG. 1 ; this remote control is a component of the exemplary FIG. 1 appliance; FIG. 4A is a plan view of a keyboard; this keyboard is a component of the FIG. 1 appliance; FIG. 5 shows, diagrammatically, what happens when the appliance of FIG. 1 is switched from one of its operating modes to a different one of those modes; FIG. 6 shows, diagrammatically, a representative navigational chart which includes an introductory video and a hierarchy of menus that can be quickly and easily navigated by a user of the FIG. 1 system to reach information of interest stored on a laser readable disk component of that system; FIGS. 7-10 depict a representative set of menus and displays of information which would be displayed to a user following the FIG. 8 navigation chart to reach information of interest; in this example dry and bottled goods with which a pantry might be stocked are displayed; FIG. 1 1 shows how a user of the FIG. 1 system can browse the pages of a web site using only the remote control (or keyboard on onboard controls) of that system; and FIGS. 12-14 show pictorially a representative set of screens that might appear if one were using the FIG. 1 appliance to browse the Internet using the protocol shown in FIG. 11. DETAILED DESCRIPTION OF THE INVENTION One currently representative and important application of the present invention is the provision of appliances which are designed for use in a kitchen. A system or appliance suitable for this (and other) applications of the invention is illustrated in FIG. 1 and identified by reference character 20. T ELEVISION CD INTERNET APPLIANCE SECURITY How appliance 20 functions in each of these modes is described above in that section of this specification entitled SUMMARY OF THE INVENTION. The major components of system 20 are: an integrated unit (or module) 22, a remote control 24, and a laser readable disk 26. As mentioned above, disk 26 may be a conventional CD or other optically readable disk from which an appliance user can retrieve information on an available task or subject. Examples only are Video 1.1, Video 2.0, DVD, and CDI disks. The illustrated system 20 also has an optional keyboard 28. This keyboard is employed by a system user with system 20 in its INTERNET mode of operation in sending e-mail messages, to reach web sites which cannot be accessed by clicking on a link on a home page 30 (see FIG. 14) of controlled context, and to carry out other functions as described in copending application No. (Attorneys' Docket No. 518120-0035) filed 17 December, 1999. Integrated unit 22 includes a television unit 32 which has a CRT (cathode ray tube) with a screen 33 (or a LED or other display) and a video compact disc player 34 (or other player for laser readable disk) both housed in the same cabinet 36. Conventional onboard controls 38 for television 32 are located on the front panel 40 and the right-hand side panel 42 of cabinet 36, and onboard controls 44 for the disc player 34 are also located on front cabinet panel 40. A conventional tray-type loader 46 (See FIG. 3 A) is used to load disc 26 into player 34. The operating components of integrated unit 22 and ancillary items activated in different operating modes of system 20 are depicted schematically in FIGS. 2, 3 A, and 3B and collectively identified by reference character 56. These components include a mode selection register 58 and a video/audio switch 59, both activate when a particular one of the system 20 operating modes is selected to channel the input available in the selected mode to the screen 33 of system 20 and to speakers 60 of that system. As a single example, when the TELEVISION mode is selected, a connection to a source for a television signal such as an antenna, a cable, and/or a VCR is made through switch 59. Other Components controlled by operating system 56, in this case, in the SECURITY mode of operation, are incoφorated in an entry module identified by reference character 62 in FIG. 3A. These components include a microphone 64, a speaker 66, and an electrically operated door latch 68. Optionally located at the same entryway (not shown) as module 62 is a camera 70 which is designed to display an image of a person at the entryway on CRT screen 33. The operation of a system of the same character as the one disclosed herein is copending application No. 09/116,285 filed 16 July 1998. Other major components of the complement 56 of operating components, located on an interface board 72, are listed below along with the function of each component. Also included in, on operatively associated with interface board 72, are the following additional components: It was pointed out above that appliance 20 can transmit and receive data via a telephone line and cell phone linkups. The telephone line is shown in FIG. 3A and identified by reference character 99. As shown in FIG. 3A, system 20 also has a USB port 100 as well as links (or connections) ( 102, 104, and 106) for transmitting appropriately formatted data to a printer and to video and audio devices which are not components of the appliance. Appliance 20 preferably also has an Ethernet port 108. This: (1) allows appliance 20 to be networked to compatible appliances and (2) allows the appliance to be connected to the Internet via DSL or other broad bandwidth link. The TELEVISION, CD, APPLIANCE, SECURITY / MONITOR, and INTERNET modes of operation may be selected by the user of system 20 with push button controls 1 10, 1 12, 1 14, 1 16, and 1 18 of remote control 24 (see FIG. 4). Referring now especially FIG. 2, electronic video/audio switch 59 is shown in the interest of clarity. This switch has five positions labeled 1-5. The pressing of one of the five mode switches 64, 66, 68, 70, on 72 causes corresponding number— shown in the following table— to be placed in selection register 58. Video switch 59 is almost instantaneously set to the number in selection register 58, causing appliance 20 to operate in the selected mode. This use of a mode selection register and a video/audio switch to make visual and audio information available to screen 32 and speakers 98 from the appropriate source in each of the five modes of operation of appliance 20 as shown in FIG. 2 is an important feature. This arrangement allows for almost instantaneous switching from one mode of operation to another, which is important to the appliance user who would typically be frustrated if an appreciable amount of time were required to switch from one operating mode to another. Remote control 24 also has a numerical keypad 120 with push buttons ® through ® and two groups of push buttons respectively identified by reference characters 122 and 124. The push buttons of group 122 are employed in the TELEVISION mode of operation. They function in the same manner as the similar designated controls of a conventional television set. The PAUSE, REV, and FWD buttons 126, 128, and 130 of group 124 are employed in the CD mode of operation in the same manner as their conventional CD player counterparts. Considering then buttons in group 124, HOME button 132 returns the system user to the beginning of a disk and thus to the beginning of its content in the CD mode of operation for system 20. In the INTERNET mode of operation, this button returns the user to a home page such as the one identified by reference character 30 in FIG. 14. STOP button 134 is employed in the same manner as its conventional counterpart in the CD mode of operation. In the INTERNET mode of operation, this button is used to stop an operation in progress - for example, the downloading of a file from the Internet. PREVIOUS and NEXT buttons 136 and 138 are used in the CD mode of operation for the purposes described in the '947 application; and the remaining buttons in group 124 are employed in the INTERNET mode of operation, again for the purposes described in the '947 application. UP, DOWN, LEFT, and RIGHT buttons 139a...d are used with appliance 20 in its INTERNET mode of operation to move a cursor 139e (see FIG. 1) around screen 33. GO button 139f is pressed to "click on" and select an option reached by cursor 139e. Also available with appliance 20 in its INTERNET mode of operation are SCROLL UP and SCROLL DOWN buttons 139g and 139h and OPTIONS button 139i. The SCROLL UP and SCROLL DOWN buttons are employed if a page of information is too large to fit on screen 33. These buttons allow the appliance user to move the page up (or down) to bring the wanted part of the page into view on screen 33. Keyboard 28 (see FIGS. 1 and 40 has both character and function keys. The character keys - collectively identified by reference character 140 - may be those constituting a conventional QWERTY key set. The function keys include conventional Tab, Caps Lock, Shift, Control, Alt, Escape, Delete, Space, Enter, and Backspace keys 141...158 as well as an On/Off key 160. Additional function keys of the illustrated, exemplary keyboard 28 include mode switches (or buttons) APPLIANCE, TELEVISION (TV), INTERNET (NET), and buttons 162...168 and a key block 170 which includes security/monitor, talk, and unlock buttons 172, 174, and 176. Mode keys 162...168 are employed to operate appliance 20 in a selected one of its APPLIANCE, TV, INTERNET, and CD modes. The talk and unlock buttons 172...176 in set 170 are employed with appliance 20 in its SECURITY 'MONITOR mode of operation to talk to a person at the entryway and to unlock a door at the entryway. Specifically, pressing button ® on remote control keypad 120 or the like numbered button on keyboard 28 (on a like numbered onboard control) allows the appliance user to talk to a person (or persons) at the entryway. Pressing button © disengages lock 68 (fig.2), allows the person or persons at the entryway to enter. This just described mode of operation of appliance 20 is entered when the door bell rings. Pressing SECURITY/MONITOR mode switch 172 turns on a camera in a monitored area— for example, an entryway or a baby's nursery. Operation of an appliance of the character disclosed herein in a SECURITY/MONITOR mode is described in detail in copending application No. 09/1 16,285. Keyboard 28 also has a number of other function keys collectively identified by reference character 178. These keys are labeled and they have the same functions as the like number buttons on remote control 24. When a character or function key on keyboard 28 is pressed, a coded electrical signal unique to the selected character or function is generated and converted to a correspondingly coded IR signal which is transmitted to appliance module 22. The IR signals are generated by LED's mounted at the two end walls 184 and 186 and the back wall 188 of the keyboard. These LED's are represented in FIG. 1 by arrows 190, 192, and 194. Consequently, and because the signals are in the IR range, a usable signal will be transmitted to appliance 20 essentially without regard to the angle through which keyboard 28 might be rotated relative to the infrared radiation receiver 84 of the appliance 20. Keyboards of the character described above are disclosed in copending provisional patent application No. 60/115,006 filed 6 January 1999 and in copending patent application No. (Attorney's Docket No. 518120-0035) filed 17 December 1999. It was pointed out above that appliance 20 may be used in its CD mode to retrieve information from a laser readable disk. Specifically, remote control 24 (on keyboard 28) is employed to navigate through a hierarchical array of menus written to the disk to retrieve information on a selected subject or task from compact disc 26 and to display that information on the screen 33 of integrated unit 22. Appliance 20 can be configured to display either an introductory video 203 on a top level menu 204 when the CD mode of operation of appliance 20 is selected. Information is reached by making choices. Appliance 20 may be programmed to bring up either an introductory video 203 on a top level menu 204 when the CD mode of appliance 20 is selected. In either case, the appliance user selects a numbered choice from the top level menu, bringing up a second level menu, 206, also with numbered choices. This process is continued until the information of interest— typically in the form of a video clip— is reached and displayed on screen 33. In the representative scenario depicted in FIG. 6, the appliance user can navigate from a second level menu 206 downwardly through second level menu 206 and a third level menu 208 to reach information of interest (screens 210 and 212). A specific example involves the retrieval of information on stocking a pantry from laser readable disk 26. The top level menu 204 is shown in FIG. 7. The user selects ® from this menu, bringing up second level menu 206 (FIG. 8). From this menu, the user selects ®. This brings up the wanted information— screen 210, FIG. 9, and screen 212, FIG. 10. In this particular example only a second level menu is accessed to retrieve the wanted information. In other instances, the wanted information be reached directly from the top level menu 204 or from a third or lower level menu. Remote control 24, keyboard 28, or onboard controls 38 may be used to navigate chart 202. Scroll buttons 139h (remote 24, FIG. 4) or 209 (keyboard 28, FIG. 4A) or a button of that character (not specifically shown) in the complement 38 of onboard controls can be used to move from the first screen of information 210 to the second screen 212. RESTART, BACK, and NEXT (or FWD) buttons as described above can be used to navigate up and down the navigation chart and to return (in this typical case) to top level menu 204. Additional information on the just-described method of retrieving information from a laser readable disk of the character disclosed herein may be found in U.S. patent No. 5,599,234 issued 3 March 1998. This unique feature is another one which makes system 20 easy and convenient to use and therefore acceptable to a person without technical training or inclination and with only the instruction provided by an introductory video 212 (see FIG. 6). The remote control 28 also has the following buttons 130 and 128 employed in the CD mode of operation in retrieving selected items of information from an appropriately coded disk as follows: FWD— advances to the next lower level of menus PREVIOUS— returns to the preceding higher level of menus In the APPLIANCE mode of operation, GSM module 88 establishes telephonic communication between appliance 20 and a remote repair/service facility. Messages regarding problems in an appliance monitored by appliance 20 are conveyed in this manner to the remote facility. In the INTERNET mode of operation of system 20, the user can navigate through linked web site pages to information of interest. A representative set of link pages is shown in FIGS. 1 1 A, 1 IB, and 12 and identifiably by reference character 214. Details of the illustrated hierarchy— which among other things, allows one to order groceries online— and the steps employed to reach this goal by navigation through the levels of the hierarchy with remote control 24 are described in the '047 application except that the choices on the web site pages are numbered so that they can be selected with correspondingly numbered buttons in the numerical keypad 120 of remote control 24. As suggested above, remote control 24 can be used to jump from the home page of an appropriate web site to other web site pages. FIG. 13 shows how this is accomplished in one representative application of the present invention. Remote control 24, keyboard 28, on onboard controls 38 can be employed to log onto and navigate (or browse) the Internet. First, the system user logs onto the Internet by pressing the INTERNET button 118 on remote control 24. This opens or brings up the home page 30 of the web site (see FIG. 14). Next, the user presses numbered button ® in numerical keypad 120 of remote control 24. This builds a new URL, bringing up a new web page 219 (see FIG. 15). If a number is not pressed, the operation will simply time out and return the user to home page 30. From web page 216, the system user can jump to yet another page— e.g., the page identified in FIG. 16 by reference character 218— by pushing a different one of the ten numbered buttons in the numerical keypad 120, here push button (6). This brings up a third web page 220. In this instance, if a second numbered button is not pressed, the operation will again time out with the system user being returned to web page 216. This sequence of steps can be repeated (if they are available) to bring up a maximum of ten sequentially linked pages. This limit is imposed by the number of buttons on the remote control keypad 120 and the desirability of avoiding the need to press more than one numbered button to initiate a particular action. Continuing, it may be that a link selected by the system user leads to a page or web site not which is not linked to one of the web site pages 30, 216, or 218. If this happens, the operation times out; and the connection to the Internet is closed. If the link is available, the system user is instead returned to the last web site page, and the user can press a numbered button to bring up another web page. Alternatively, if the user of appliance 20 wishes to visit a web site not linked directly or indirectly to home page 30, the user simply uses keyboard 28 to type the URL of the wanted web site and presses GO button 220 (Fig. 4A) to jump to the web site. Other linked sites can be reached by using UP, DOWN, LEFT, and RIGHT buttons 222...228 place cursor 139e (FIG. 1 ) on a selected link and then pressing the GO button 230 to bring up the selected link. Another important feature of the present invention if that appliances embodying the principles of the present invention the system user is returned to where he was in a particular operating mode if he switches from that mode to another mode (or series of modes) and then back to the first mode. This second novel, and important, operating feature invention is depicted in graphic form FIG. 5 and elaborated upon in the following table: The foregoing is not to be interpreted to mean that novel and important advantage of appliance 20 (and other appliances involving the principles of the present invention) can be obtained only if operation is switched from a first to a second mode and then back to the first mode. The appliance will operate as described no matter how many mode changes are made before the exited mode is reentered. It is also to be understood that, to meet the needs of a particular market, one or more of the five operating modes of system 20 can be disabled. Disabled modes can be enabled as disclosed in copending provisional application number 60/1 15,008 filed 6 January 1999. The following patent documents referred to above are hereby incoφorated in this disclosure by reference thereto: U.S. patent No. 5,724,102 issued 3 March 1998. U.S. patent No. 5,801.784 issued 1 September 1998. Copending patent application No. 09/046,947 filed 23 March 1998. Copending patent application No. (Attorney's Docket No. 518120-0035). Copending application No. 09/116,785 filed 16 July 1998. Copending application No. 09/116,825 filed 16 July 1998. Copending application No. 60/115,008 filed 6 January 1999. As will be apparent to the reader, the invention may be embodied in specific forms in addition to those discussed above without departing from the spirit or essential characteristics thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description; and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
