Guide to Windows Shortcut Keys
Here I've tried to document the shortcut keys that can be used in nearly all versions of Windows. The reason for using them is simple: speed. You don't need to use the mouse to get around and get things done. Every time you move your hand from the keyboard to the mouse and back again, you lose a slice of time. In fact, Windows was designed for either a keyboard OR a mouse when it first came around, and many a software developer will tell you they prefer to interact with the computer this way.
Make it a habit to practice one or two shortcut keys at a time, until they become natural. Once you get used to it, you'll swear off your rodent. Really. It makes you that much more efficient. Many of my friends think that I'm fast, and while there may be some truth to it, it's more to do with shortcuts using the keyboard. Think about it logically: every time you move your hand from the keyboard to the mouse, you are wasting time. Further, with keyboard shortcuts, you have no need to "aim" the mouse pointer at something to get it done.
Controlling application windows
Moving, copying, and cutting text, images, and files
Cut, copy and paste. These keys are nearly universal, and can cut, copy and move nearly anything you can imagine, from an email address to the biggest file. These are probably the most powerful and overlooked keystrokes in the history of computing, and even word in some older DOS applications (WordPerfect 5 for example).
Oh, crap! I didn't mean to do that!!
Navigating without a mouse
Pressing the TAB key will change from Yes, to no, and then finally to cancel....and to actually push in the correct button, keep reading...
CTRL+F4 (alternately CTRL+SHIFT+F4)
Closes the current document window. Handy in Microsoft Word, Microsoft FrontPage, and most multi-document applications. This works when the program you are using has a Multiple Document Interface (MDI), meaning that many different documents can be opened in the same application Window. Later versions of Microsoft Office have the SDI (Single Document Interface) and it works equally well.
Closes the current application (program). Keep pressing it enough, and it will close all open programs - you can even use it to close Windows itself! Actually, once all applications are closed it pops up with the now-familiar "What do you want the computer to do" screen.
