Dell XPS 13 running Ubuntu 14.04 LTS. I use the Home and End keys frequently. (Seems most people don't use these keys much anymore.) Unfortunately, because it's such a small computer, Dell put Home and End on top of the left and right arrow keys, requiring holding the Fn key down to get Home and End.
There's a Ctrl key right next to the cursor keys. I never use this key, as I have CapsLock mapped to Ctrl. I'd like it to behave as a Fn key so I can press Fn Left (Home) and Fn Right (End) using one hand.
Is there any way to do this?
EDIT: I ran both showkey and xev, as suggested by @A.B.'s comment, and the Fn key does not trigger any output. I have a feeling that means my request is impossible.
