sending key strokes to applications

[geisj at pagestation.com (Jerry Geis)]

All,

Is there a way to send key strokes to applications under X?
I wish to send F11 to mozilla/firefox to put it in full screen mode.

Not sure why there is not a command line parameter to do it.

Just some utility that could be run that sends a keystroke to an 
application.

THanks
