Remapping keyboard keys in Linux

For some reason, Delete and Insert keys are combined on my laptop (ASUS). You have to press fn key and Delete key to get Insert.

The simple system-wide solution to this is the xmodmap utility; this utility allows you to map any key to any other key.

In my case, I decided to use Pause key instead of Insert (how often do you need the Pause key anyways?), and this is all you have to do:

xmodmap -e "keysym Pause = Insert Insert Insert Insert"

Add it to rc‘s to get this automatically run on system startup.

Note: in the xmodmap command above, the 1st Insert is a key press with no modifier pressed, 2nd with Shift, 3rd with Ctrl, 4th with Ctrl+Shift.
