Using Ctrl+V to paste unformatted text by default in OpenOfficedotorg's Calc

"Autohotkey!

^+v::
bak = %clipboard%
clipboard = %bak%
Send ^v
return

That would replace Control-Shift-V with an ""unformatted"" paste, globally.

If you wanted it OOo Calc only, you'd do something like:

#IfWinActive, ahk_class [something]
^v::
bak = %clipboard%
clipboard = %bak%
Send ^v
return
#IfWinActive

Where [something] is the window's Class name, which you could easily find out with AHK's bundled Window Spy. (This one would actually replace Control-V (^ means control, + means shift), but doing that systemwide is a bad idea)"
