The Function Keys
In Microsoft Windows, key functions vary from application to application. There is, however, some common functionality between programs. Common function key tasks include:
F1: The F1 key is almost universally used to access help files. By pressing WINDOWS KEY + F1, you can access the Windows help and support center.
F2: The F2 key is used to rename the selected file or object.
F3: The F3 key is often used to access the search function of an application. On the desktop, F3 will call up the detailed Search Results window.
F4: Typing ALT + F4 will close the currently active program.
F5: This key will refresh the contents of a dialog box (e.g., Save As). In most browsers, F5 will refresh the currently displayed Web page.
F7: Sometimes used to call the Spell Check function of an application. Microsoft Word and Open Office both support this command.
F10: The F10 key makes a program’s Menu Bar active. SHIFT + F10 will display an item’s shortcut menu-the equivalent of right clicking on an item.
F11: This key is used in most browser programs to switch into full-screen mode
Windows doesn’t use all of the function keys. You can take advantage of this by assigning a program to an “empty” function key.
F8, F9 and F12 are good candidates.
