I saw the vim wiki tips and it says that in order to remap Esc to CAPS LOCK you have to edit the following windows code:
REGEDIT4
[HKEY_CURRENT_USER\Keyboard Layout]
"Scancode Map"=hex:00,00,00,00,00,00,00,00,02,00,00,00,01,00,3a,00,00,00,00,00
Is it possible to remap Esc to CAPS LOCK by only adding or modifying lines in the _vimrc?
I recommend that you use AutoHotkey for this.
You can do a per-application hotkey change:
SetTitleMatchMode,2
#IfWinActive,VIM
CAPSLOCK::ESC
return
#IfWinActive
CAPSLOCK::CTRL
return
This script, for example sets caps to escape in vim, and control everywhere else.
