We’ve shown you many alternate uses for your Caps Lock key in the past, but if you like the idea of Chrome OS’ search key (which replaces Caps Lock on the CR-48), here’s how emulate it on Windows using AutoHotkey.
If WinExist(“ahk_class Chrome_WidgetWin_0”)
Run “C:\Users\Whitson Gordon\AppData\Local\GoogleChrome\Applicationchrome.exe”
Note that you'll want to change "Whitson Gordon" to your own user name in the path to Google Chrome.
OS X, unfortuntaely, won't let you maps the Caps Lock key to a specific function alone. However, with a bit of tweaking, we can get it so a simple shortcut like Caps Lock+Space will work just fine. First, create a new AppleScript with this code as the body:
tell application "System Events"
tell application "Google Chrome" to activate
keystroke "t" using command down
keystroke "l" using command down
Now, head into System Preferences > Keybaord and hit the Modifier Keys button. Change the Caps Lock key to perform a different action (I chose Control). Open up Quicksilver and create a new trigger as described here. Use something like Control+Space as your Hot Key. Now, Caps Lock+Space will open up a search-ready Chrome for you.

Update: If you're a Firefox user, AutoHotkey ninja Platypus Man has already created a tweaked version that works in Firefox. If you're using Firefox on the Mac, just replace "Google Chrome" with Firefox.
