A regular request from readers (not users of Macs, though) is an explanation of what on earth the "F" keys at the top of the keyborad are for.  They are mysteriously labelled F1, F2, F3 and so forth.

Well, here is a short list of some of them, to whet your appetite:

F1 - press this and the Help box should appear - this works with most programs

F2 - In Word, Ctrl + F2, releases the Print Preview window

F3 - used to open a "Search" window

F4 - In Word, F4 will repeat the last action. If you just typed a long bit, and want to type it again (but why?), just pressF4.

F5 - F5 will refresh the content on the web page you are looking at, in case it has changed since the last time you looked.

F6 - Moves the cursor to the address bar and highlights the current address.

F7 - In Word, F7 automatically runs the Spellchecker, and Shift+F7 activates the Thesaurus

F11 - switches back and forth from Full Screen Mode. Try it and see what changes.

You are unlikely to break anything by having a go, so experiment - and let me know if you discover something amazing.
