To Mike 22 :
I still use Sensiva vith AutoCAD 2005 and AutoCAD 2009 on Windows XP
and I tried to use "keystrokes" in sensiva : it works with autocad !
For exemple, I draw a "Z" with sensiva which understand CTRL+ALT+Q which seems cut between 2 points in autocad ;-)
So you can try tu use keystrokes with sensiva and Firefox :-)
