I was wondering if there was an open source program that would allow me to have a certain keystroke/key combination pressed every say, two seconds or so. Forgive me, I merely do not know what a program like this would be called. Thanks!

Yes, there is an open source program to create fake keyboard and mouse inputs for GNU/Linux. It is called Xdotool Install Xdotool.

To press a key (in this exemple 'a') every two seconds you can use a script like this :


while true; do
  xdotool key a
  sleep 2

If you make this script executable and you add it on Startup Applications it will press 'a' every two seconds.

Here is the documentation for Xdotool :

And here is the specific part on keyboard commands :

If you are using a Logitech keyboard, there is a package called "g15macro" in the Ubuntu repo that is useful. Otherwise there are other open source applications such as "xmacro" and "xnee".
