Some of these shortcuts even pre-date Windows ... they were in the early word processors and text editors that Word and Excel are built upon. The keystokes were 'inherited' by lots of other programs that have succeeded them. They are so ingrained into the software that often developers forget to document them!
Try them in Word for Windows, Write, WordPad and even little old Notepad, for they will all use some of them. Sadly it's not 100% consistent, but they are always worth trying.
Moving
* One word to the right Ctrl+<right arrow>
* One word to the left Ctrl+<left arrow>
* Start of line Home
* End of line End
* Up one screen PageUp
* Down one screen PageDown
* Top of Screen Ctrl + PageUp
* Bottom of Screen Ctrl + PageDown
* Beginning of Document Ctrl + Home
* End of Document Ctrl + End
+ means to press the keys at the same time. For example, 'Ctrl + PageUp' means to hold down the Ctrl key while pressing the PageUp key.
Deleting
* Delete word to left Ctrl + Backspace
* Delete word to right Ctrl + Delete
Clipboard
* Copy selection Ctrl + C
* Cut selection Ctrl + X
* Paste selection Ctrl + V
* Undo last of the above Ctrl + Z (general Undo in MS Office)
These clipboard functions are very handy in all sorts of places, for example, you can copy a Web address from an email message or document into the 'Address' part of your browser. Almost any place where you might move info from one program to another can be done using these keys. Because of their more global application, they are better habits than some equivalent keystrokes (Shift + Delete to cut etc) that are not as widely recognized. In Office 2000 you have the 12 item clipboard that we've discussed previously - the same shortcuts apply. Most of these shortcuts are pretty obvious and have an internal logic that becomes apparent once you give them a try. Most have some link between the shortcut letter and the name (Ctrl + C = Copy). But others are less obvious -- the clipboard keys seem weird until you realize they are the bottom left four letters on a standard QWERTY keyboard.
