Most browsers will have a button labeled 'FIND' or you might find it under the 'EDIT' menu. When the window pops up, enter the word you want to find in the text field and press the 'OK' button. When the window goes away, the text you typed should be selected if found. Additional help on the search or find features of your particular browser may be found under the 'HELP' menu, wherever there's a question mark, or by pressing the 'HELP KEY' on your keyboard. Frames are sections of a web page that allow the display of other web pages within them.
Frames allow the use of multiple, independently controllable sections on a single web page.
You may wish to download the latest version of Netscape Navigator or Microsoft Internet Explorer. My Browser is newer than that. Some versions of Microsoft Internet Explorer allow frame support to be turned off. Check under Preferences, Options, or Internet Options, depending on which version you are running.
