[Note: Edited on 2010-02 to switch the order of the shift and command key modifiers. Apparently, Mac OS is particular about the order.]

I'm a longtime Windows user who recently purchased a Macbook. Overall I'm very impressed with the machine, but it does have a learning curve, especially for the key bindings.
The first thing I noticed was that the Macbook does not have the Del and Ins keys at all, and the Home, End, PageUp and PageDown keys require pressing 'Fn' and then an Arrow key (which is understandable because the keyboard on a small Macbook is somewhat cramped -- also, I've asked a couple users who have not used PCs much before using a Mac, and they did not even know these keys existed, or what they would do with them)
However, when I'm not on the road, I like to use a nice full sized Microsoft Natural Keyboard, to reduce tendinitis. As a (former) hard-core programmer, I very extensively use the Home, End, PageUp and PageDown keys to quickly navigate code or text documents. I was very dismayed to discover that Apple pretty much doesn't do anything with these keys.
In hunting through all the configuration options, I noticed that you can reconfigure a lot of key mappings through the System Preferences utility (go to the apple in the upper-left corner, select System Preferences..., click on Keyboard & Mouse, and click the Keyboard Shortcuts tab). This was useful for a start, but I quickly determined that the Mac wouldn't allow me to bind keys to any of the 6 special keys (Home, End, PageUp, PageDown, Delete, Insert). This made me sad.
I did discover, however, that it is possible to switch the Control and Command keys. This is a big help because now all the windows favorites like Ctrl+c for copy, Ctrl+v for paste, Ctrl+x for cut, and Ctrl+z for undo now work the same on both systems. I still switch frequently between Windows and Mac platforms, so it's very nice to have the same key mappings.
Most recently, I discovered that there is a special file you can create that allows special mappings to the 6 special keys. This made me happy. I was now able to get much closer to having a unified key mapping. For more details, see
this article.
To do this, create a new file called ~/Library/KeyBindings/DefaultKeyBinding.dict and put the following text into it (You'll probably have to create the directory the first time -- this is okay).
/* ~/Library/KeyBindings/DefaultKeyBinding.Dict
This file remaps the key bindings of a single user on Mac OS X 10.5 to more closely
match default behavior on Windows systems. This particular mapping assumes
that you have also switched the Control and Command keys already.
This key mapping is more appropriate after switching Ctrl for Command in this menu:
Apple->System Preferences->Keyboard & Mouse->Keyboard->Modifier Keys...->
Change Control Key to Command
Change Command key to Control
This applies to OS X 10.5 and possibly other versions.
Here is a rough cheatsheet for syntax.
Key Modifiers
^ : Ctrl
$ : Shift
~ : Option (Alt)
@ : Command (Apple)
# : Numeric Keypad
Non-Printable Key Codes
Up Arrow: \UF700 Backspace: \U0008 F1: \UF704
Down Arrow: \UF701 Tab: \U0009 F2: \UF705
Left Arrow: \UF702 Escape: \U001B F3: \UF706
Right Arrow: \UF703 Enter: \U000A ...
Insert: \UF727 Page Up: \UF72C
Delete: \UF728 Page Down: \UF72D
Home: \UF729 Print Screen: \UF72E
End: \UF72B Scroll Lock: \UF72F
Break: \UF732 Pause: \UF730
SysReq: \UF731 Menu: \UF735
Help: \UF746
NOTE: typically the Windows 'Insert' key is mapped to what Macs call 'Help'.
Regular Mac keyboards don't even have the Insert key, but provide 'Fn' instead,
which is completely different.

"@\UF702" = "moveWordBackward:"; /* Cmd + LeftArrow */
"@\UF703" = "moveWordForward:"; /* Cmd + RightArrow */
"@$\UF702" = "moveWordBackwardAndModifySelection:"; /* Shift + Cmd + Leftarrow */
"@$\UF703" = "moveWordForwardAndModifySelection:"; /* Shift + Cmd + Rightarrow */
}Remember: These key mappings assume that you've switched Control and Command. If you don't want to make this switch, replace each @ (command) with ^ (control).
Here are steps to take to apply these changes:
- Open TextEdit under the Applications folder. If TextEdit was already open, create a new document using File->New. There should be a window labeled 'Untitled'.
- Select the text within the window above, copy it, and then paste it into your new TextEdit window.
- In TextEdit, convert this to plain text (the default is rich text) by selecting Format->Make Plain Text.
- Next, select File->Save As... In the "Save As" dialog box, navigate to your home directory (look under PLACES on the left side for a house picture that has your name next to it). In your home directory, double-click on the Library folder. If you see a KeyBindings folder then double-click on it. If not, then click on "New Folder" (within the Library directory), name the new folder KeyBindings (with no space), and then double-click on it. Type
DefaultKeyBinding.dict for the filename (at the top) and then click Save.
- Warning: TextEdit will sometimes try to 'help' you by appending a .txt extension to the filename. Make sure this doesn't happen. If asked to use a .txt extension, tell TextEdit to instead use .dict. It will not work if you use .txt. If you have trouble, see comment by Nathan below.
- Before these changes take effect, you need to log out and then log back in.
There you have it! I know this emulation isn't perfect (not all applications honor this mapping), but it's a good start. Please drop comments if you have any questions or suggestions for improvements.
