RSI Prevention in Sublime Text

I have recently spent some time updating my dotfiles repo and have taken a lot of inspiration from some of the repositories listed by github.

I especially liked Yan Pritzker's dotfiles, and his key bindings for vim.

Particularly useful is the remapping of _ and - to ⌘+k and ⌘+K respectively. I wanted to recreate this in sublime text and which is pretty easy:

If you are on OS X hit Sublime Text > Preferences > Key Bindings - User

To this file add the following lines (your hands will thank you)

{
    "keys": ["super+k"], 
    "command": "insert", 
    "args": { "characters": "_"}
},
{
    "keys": ["super+shift+k"], 
    "command": "insert", 
    "args": { "characters": "-"}
}

Key bindings are pretty easy + powerful to create in ST, check out the list of commands that you can use in conjunction with the key bindings file.
