How to launch a command at startup? <solved>

[declan]

My scroll lock key doesn't work and after alot of searching I found out that I had to find an unused modifier and assign the key to it!

Mod3 is free so I now need to add this command somewhere to launch it at startup:

add mod3 = Scroll_Lock

but I don't know where to add it! I tried adding it to .xsession in my home directory but this stopped Linux from booting. I then added it .xinit but it didn't execute.
Where should I be adding it?

Thanks!

OK, solved this!
Created the following file and added it do $HOME/.kde/Autostart/

#!/bin/bash
xmodmap -e 'keycode 78 = Scroll_Lock'
xmodmap -e 'add mod3 = Scroll_Lock'
exit 0
