provide automatic keyboard and mouse input in X

Do you need programmatically schedule some keyboard and mouse input in linux?
Look no further
xdotool is the solution :-)
the installation is as easy as typing

sudo apt-get install xdotool

and assuming you need to do a (left) click on the mouse but only 10 seconds after you left your desk:

sleep 10 ; xdotool click 1

Bonus
obviously it also work if you have to send the commands in a RDP session :-)
