It allowed me to write the following, which is the "Clipboard Swap" command I thought would be occasionally useful. (Clipboard Swap: It copies highlighted text to the clipboard while replacing it with the current clipboard contents. It's activated by Windows-v).
tempClip := clipboard
tempClip2 := clipboard
clipboard := tempClip
clipboard := tempClip2
Just copy the script, paste it into, eg, ClipboardSwap.ahk , and then run that file with AutoHotKey (you may want to include it in your Startup folder so it's loaded every time).
Inasmuch as the above code is copyrightable, I hereby relinquish it to the public domain.
