Changing Alt-Tab behavior (Fedora)
 

Hello everyone,

This is my first post here,I am a student who have recently started working with linux(Fedora 4 to be specific).I am quite new to linux still, i did few days of research and googling but the stuff i found haven't been very helpfull so far.

I am working with some voice recognition software and would like to change a little what happens when kernel receives an interupt key press (alt tab)
I will simulate a keyboard alt tab key pressed event
which will be triggered by voice instead of actual key press.

My question is where would i find more inforation on what exactly happens when a key is pressed.
I would like to add numbers to the small box with tasks that pops up when alt tab is pressed and i would like it to pause awaiting another voice command from user (the command will be label number which in turn will switch to that task window).

So i would like to find out,understand and modify the code that is executed after the keyboard event "alt tab" is recognized and interupt handler forwards the alt tab command to execute the code to pop up the task window.

Or if what happens when you press alt tab cannot be modified would it be possible to add a system call to perform exactly what pressing alt tab does + my modification?

Thank you!
P.S sorry if this is to long
