AutoHotKey scripts to map H J K L to arrow keys when holding ⇪ Caps Lock
vim_caps_lock_map.ahk maps Escape to Caps Lock and H J K L keys to arrow keys when holding Caps Lock.
vim_escape_map.ahk is the same but doesn't remap Escape to Caps Lock, so mappings work when holding Escape.
This is useful if you want to use another app like SharpKeys to remap Escape to Caps Lock on a deeper OS level than AutoHotKey.
Caps Lock + B is mapped to Page Up.
Caps Lock + F is mapped to Page Down.
