     DETAILED DESCRIPTION 
     A scrollable desktop interface may allow multiple open applications on an electronic device such that some open applications are out of view, and a user may scroll to them. For example, the scrollable desktop may appear to be an infinite desktop where a portion of the desktop is in view at a given time. A scrollable desktop interface may allow a user to keep more applications accessible than a tab based application access configuration limited to the length or width of the display screen space. 
     In one implementation, a navigation portion of a desktop user interface provides a key for navigating a scrollable desktop. For example, the navigation portion may be a non-scrollable version of the scrollable desktop showing the scrollable desktop as if it were a circular desktop unwrapped. In some implementations, the scrollable desktop is an infinite desktop from left to right that does not allow for a circular navigation where the two sides are connected, and the navigation portion may show the scrollable desktop portions that are both in view and portions that are out of view to the left and right of the in view portion. The open applications on the scrollable desktop may appear as miniature representations on the navigation key. The navigation key may include the open applications in a manner that makes them appear in the same way as on the scrollable desktop as a smaller version. For example, the navigation key may preserve the relative size of the open applications and the relative distance between them. 
     The navigation portion may include a selection object showing the portion of the scrollable desktop in the current view on a display device to allow a user to orient the position on the navigation portion. For example, the selection object may provide an outline over the portion of the navigation key in the current view of the scrollable desktop. In some cases, a portion of an open application may be in view and a portion of the open application may be out of view depending on the current position of the scrollable desktop, such as where a user has scrolled to a position where an open application is on the edge of the current view. 
     The navigation key may provide a better user experience with an electronic device. A navigation key may allow for a scrollable desktop for accessing more open applications while maintaining a sense of position on the scrollable desktop and providing information about the contents of the scrollable desktop out of view. 
       FIG. 1  is a block diagram illustrating one example of an electronic device  100 . The electronic device  100  may be, for example, a desktop, laptop, slate, or mobile computing device. The electronic device  100  may include a machine-readable storage medium  101 , a processor  104 , and a display  105 . The display  105  may be, for example, a display that is part of the electronic device  100 , such as a mobile phone or tablet computer screen, or a separate display device connected to the electronic device  100 , such as a monitor connected to a desktop computer. The display  105  may display information to a user interacting with the electronic device  100 . For example, the display  105  may display a user interface, such as a desktop user interface, for allowing a user to access applications for use. 
     The processor  104  may be any suitable processor, such as a central processing unit (CPU), a semiconductor-based microprocessor, or any other device suitable for retrieval and execution of instructions. In one implementation, the electronic device  100  includes logic instead of or in addition to the processor  104 . As an alternative or in addition to fetching, decoding, and executing instructions, the processor  104  may include one or more integrated circuits (ICs) (e.g., an application specific integrated circuit (ASIC)) or other electronic circuits that comprise a plurality of electronic components for performing the functionality described below. In one implementation, the electronic device  100  includes multiple processors. For example, one processor may perform some functionality and another processor may perform other functionality described below. 
     The machine-readable storage medium  101  may be any suitable machine readable medium, such as an electronic, magnetic, optical, or other physical storage device that stores executable instructions or other data (e.g., a hard disk drive, random access memory, flash memory, etc). The machine-readable storage medium  101  may be, for example, a computer readable non-transitory medium. The machine-readable storage medium  101  may include instructions executable by the processor  104 . The machine-readable storage medium  101  may include instructions to be executed by the processor  104  to create a desktop user interface to be displayed on the display device  105  for allowing a user to access applications for use. The processor  104  may execute instructions to cause the created user interface to be displayed. 
     The machine-readable storage medium  101  may include scrollable desktop area instructions  102  and navigation area instructions  103  executable by the processor  104 . The scrollable desktop area instructions  102  may be instructions to create a scrollable desktop. The scrollable desktop may include multiple applications where some are in view and others are out of view. The user may scroll across the scrollable desktop to move the desktop position to bring other open applications in view. For example, a user may have a desktop with an image editing application and word processing application in view, and a video application may be out of view such that a user may scroll to view it. The scrollable desktop may preserve characteristics of the open applications that are out of view. For example, the size of the open applications and distance between them may be set by the user and preserved whether or not a particular open application is in or out of view. 
     The navigation area instructions  103  may be instructions to create a navigation area of the desktop. The navigation area may provide a view of the complete scrollable desktop as if it were stretched out. The navigation area may provide a smaller version for allowing a user to view the current view of the scrollable desktop in context of the scrollable desktop as a whole. For example, the navigation area may show both areas of the scrollable desktop in the current view and areas of the scrollable desktop out of the current view. The navigation area may make the user aware of the open applications and their position on the scrollable desktop, allowing a user to know now to scroll to the other applications. The navigation area may also show the relative size of the open applications and the relative distance between them. 
     In one implementation, the navigation area includes a selection area to show which portion of the scrollable desktop is currently in view. The selection area may outline the portion of the navigation area in the current view to provide context to the position of the scrollable desktop in the current view. For example, a particular instance of a word processing document may be the one in view, and the navigation key may show an outline around that particular instance. 
       FIG. 2  is a flow chart  200  illustrating one example of a method to create a user interface with a scrollable desktop and a navigation key. For example, a scrollable desktop may allow for a desktop to be larger than a display device such that some items may be out of view, and a user may scroll to other portions of the desktop not in the current view. A navigation key may provide a key for navigating the scrollable desktop. For example, the navigation key may be a smaller version of the scrollable desktop showing the scrollable desktop as if it were unwrapped or fully in view. The navigation key may allow the user to see other open applications not in the current view of the scrollable desktop and to see the position of the current view in the scrollable desktop. The method may be implemented, for example, by the electronic device  100  from  FIG. 1 . 
     Beginning at  201 , a processor, such as the processor  104 , creates a scrollable desktop portion of a user interface to display open applications for use. The scrollable desktop portion may be a desktop user interface displayed on a display device. For example, the desktop user interface may be a default or background user interface. The desktop user interface may be initially displayed, and a user may access applications from the desktop user interface, such as by selecting shortcuts or menu items. The open applications may be any suitable applications available on the electronic device. As an example, the current view may have a word processing application open, and a user may scroll to another portion of the desktop to access an email application to send an email. 
     The scrollable desktop may allow the desktop user interface to extend beyond the dimensions of a display device. For example, a portion of the scrollable desktop may be hidden from view and may be accessed by scrolling to the position of the hidden items on the scrollable desktop. When a user opens a new application, it may be displayed on the scrollable desktop. In some implementations, the user may move or resize an open application on the scrollable desktop. The user may scroll between applications to access different applications. For example, the scrollable desktop may include a word processing document and web browser each open and ready for use such that a user may scroll between them. A user may then resize them smaller such that they both show up on a display simultaneously without scrolling between them. 
     Moving to  202 , the processor creates a navigation portion of the user interface to display representations of the open applications in view and out of view on the scrollable desktop portion and the relative position of the open applications on the scrollable desktop. The navigation portion may, for example, show a non-scrollable version of the scrollable desktop such that in some cases the entire scrollable desktop may be in view. When a user opens a new application on the scrollable desktop, a representation of the application may appear on the navigation portion in the same relative position and relative size as on the scrollable desktop. When a user closes an application on the scrollable desktop, the application may disappear from the navigation portion. The representations may be any suitable representations of the open applications. For example, they may appear as smaller versions of the open applications that provide a user with a view of the open applications currently in view and a peak of the open applications out of view. 
     A processor may determine the layout of the navigation portion in any suitable manner. The layout may be determined, for example, based on the size of the navigation portion. A user may set the size of the navigation portion, or the size may be based on the size of a display device for displaying the navigation portion. In one implementation, the processor determines the size of the visual representations of open applications based on the number of open applications such that the open application representations fit on the available space on the navigation portion. For example, the visual representations may appear larger where the amount of space in use on the scrollable desktop is smaller. The navigation portion may be resized by a user to make the visual representations larger or smaller. The relative size and position of the visual representations may remain constant to reflect the relative sizes and positions on the scrollable desktop portion. 
     The navigation portion may be in any suitable position on a user interface. For example, the navigation portion may display the scrollable desktop in a horizontal or vertical manner. The navigation portion may appear on the top, bottom, or other position of a display screen. In one implementation, the navigation portion may be positioned based on user input. For example, a user may select a setting indicating where the navigation should appear, or a user may move the navigation portion, such as by selecting it with a mouse and moving it. In some implementations, a user may select to show or hide the navigation portion, or may select to pin the navigation portion in a particular position. 
     In one implementation, the representations of open applications on the navigation portion include live images of the open applications from the scrollable desktop. For example, an open application of a web browser showing a sports game may have a visual representation showing live updates of the sports game. The live images may allow the user to see the contents of open applications that are not in the current view of the scrollable desktop. 
     Continuing to  203 , the processor creates a selection object for selecting a portion of the navigation user interface corresponding to the portion of the scrollable desktop in view. For example, the navigation portion may include a box, outline, highlight, or other item indicating a selection of the portion of the scrollable desktop in the current view. The selection object may be helpful, for example, where the same type of open application is open on different portions of the scrollable desktop. The selection object may allow a user to orient the current scrollable desktop view within the scrollable desktop. 
     Proceeding  204 , the processor causes the user interface to be displayed. For example, the user interface may be displayed on a monitor, screen, or other display device. A user may interact with the user interface, and the user interface may be updated in response. For example, a user may move the selection object, and the scrollable desktop automatically scrolls to bring the highlighted portion within the selection object into view. In one implementation, the selection object automatically moves in response to scrolling of the scrollable desktop. 
       FIGS. 3A and 3B  are diagrams illustrating one example of a scrollable desktop with a navigation key.  FIG. 3A  shows an electronic device  300  with a navigation portion  301  of a user interface and a scrollable desktop portion  302  of a user interface. The scrollable desktop portion  382  is a scrollable desktop with two open applications in the current view and a portion of another open application in view. The navigation portion  301  shows representations of the open applications in the current view and the open applications that a user may scroll to in the scrollable desktop portion  302 . 
     The selection area  303  of the navigation portion  301  shows the part of the scrollable desktop displayed in the scrollable desktop portion  302 . For example, the navigation portion  301  shows five open applications. A user may scroll across the scrollable desktop portion  302  to view the different open applications, and a user may begin using the open applications in the scrollable desktop portion  302 . For example, a user may resize an open application for use, or may use the application in a smaller size where other open applications are also simultaneously in view on the scrollable desktop portion  302 . The relative size and position of the open applications on the scrollable desktop portion  302  may be reflected in the navigation portion  302 . The selection area  303  includes a box around the three open applications in the current view of the scrollable desktop portion. The scrollable desktop portion  302  may be scrolled in such a manner that part of an open application is in view and the remaining part is not in view because the selection area  303  may reflect a position on the scrollable desktop portion  302  in addition to the particular open applications in view. 
       FIG. 3B  shows the electronic device  300  with the selection area  303  included over a different area of the navigation portion  301  because of the updated view on the scrollable desktop portion  302 . For example, a user may scroll the scrollable desktop  302 , and the selection area  303  may automatically be moved in response. The selection area  303  may orient the user to the new position in the scrollable desktop. In one implementation, a user may move the selection area  303 , and the scrollable desktop portion  302  automatically scrolls to show the portion within the selection area  303 .  FIG. 3B  shows the scrollable desktop portion  302  after a user has scrolled to the left to bring different open applications in view. The two open applications in view on the scrollable desktop portion  302  are selected in the selection area  303  on the navigation portion  301 . 
       FIGS. 4A and 4B  are diagrams illustrating one example of altering a user interface with a scrollable desktop and navigation key.  FIG. 4A  shows an electronic device  400  with a navigation portion  401  and a scrollable desktop portion  402 . Open applications  405  and  406  are in view in the current position of the scrollable desktop portion  402 . The selection area  403  shows the representation  407  of open application  405  and the representation  408  of open application  406 . A user  404  moves application  405  to the right of application  406 . 
     The navigation portion  401  may be updated to reflect the current state of the scrollable desktop portion  402 .  FIG. 4B  shows the updated selection area  403  of the navigation portion  401  reflecting the new view of the scrollable desktop portion  402 , including the new order of the open applications  405  and  406 . For example, representation  407  is shown to the right of representation  408 . 
       FIGS. 5A and 5B  are diagrams illustrating one example of resizing an open application in a user interface with a scrollable desktop and navigation key.  FIG. 5A  shows an electronic device  500  with a user interface with a navigation portion  501  and a scrollable desktop portion  502 . A selection area  503  shows the area of the navigation portion  501  in view in the scrollable desktop portion  502 . A user  507  resizes the open application  505 , also shown as the representation  506  in the navigation portion  501 , to make it appear larger. 
       FIG. 5B  shows the open application  505  resized in the scrollable desktop portion  502  and the representation  506  resized in the navigation portion  501 . In some implementations, the open application representations in the navigation portion  501  may be resized based on the number or size of icons. The relative sizes may be the same even as the size changes. The representations on the navigation portion  501  may also be resized in response to a change in size of the navigation portion  501 . The representations may be resized to maintain the reflection of the relative size and position of the open applications on the scrollable desktop portion  502 . 
       FIG. 6  is a diagram illustrating one example of a user interface with a scrollable desktop and navigation key where the navigation key includes desktop icons. For example, the scrollable desktop portion  602  includes icons  606  and  607 . The icons may be any suitable icons that may be on a desktop user interface. For example, they may be a short cut to a particular folder, document, or program. The icons  606  and  607  may remain in the same position even as the scrollable desktop is scrolled. For example, access to the icons  606  and  607  may remain when the scrollable desktop portion  602  is scrolled to a different position. The icons may be shown in the navigation portion  601 . The icon  606  may be associated with the icon representation  604 , and the icon  607  may be associated with the icon representation  605 . The icon representations  604  and  605  may be shown in a selection area  603  of the navigation portion  601  to orient the user as to the position of the open applications relative to the icons. 
     A scrollable desktop with a navigation portion may provide a user with information about options out of view on the scrollable desktop. The navigation portion may also orient a user to the current position displayed on the scrollable desktop. The navigation portion may allow the scrollable desktop to provide a better user experience due to the increased size of the desktop user interface.
