Quickly Convert Any Selection to Upper or Lower Case

In the tradition of posting my AutoHotKey hacks (Universal AutoCorrect with AutoHotKey and Wikipedia and Making the INSERT Key Useful Instead of Annoying), here's a new one that lets you easily convert text you select in any application to upper (CTRL-SHIFT-plus) or lower (CTRL-SHIFT-minus) case:

; Convert Selection to Lower Case
^+-::
bak = %clipboard%
Send, ^c
StringLower, clipboard, clipboard
Send, ^v
clipboard = %bak%
return

; Convert Selection to Upper Case
^+=::
bak = %clipboard%
Send, ^c
StringUpper, clipboard, clipboard
Send, ^v
clipboard = %bak%
return

See either of my previous posts for more detailed information on what AutoHotKey is and how to get it fired up.
