- I am rjloura (https://keybase.io/rjloura) on keybase.
- I have a public key whose fingerprint is 1C91 E340 FC48 C37C BCEE A2AE 997E 6BF0 FAEB CE04
To claim this, I am signing this object:

My chromebook doesn't have a caps lock key, it has a "search" key. When running crouton xfce4 is unaware of this key in the keybaord mappings GUI. This is how I ended up mapping the search/capslock key to escape.
KeyPress event, serial 28, synthetic NO, window 0x2600001,

XKeysymToKeycode returns keycode: 9
XLookupString gives 1 bytes: (1b)
