- Base Remapping Keys
`#{n, e, i, o}` <=> `#{h, j, k, l}`
- setting `avy` keys to the `colemak` home row keys
`#{a, r, s, t, n, e, i, o}`
- adjusting leader key to `tn`
- overriding evil org mode bindings especially for 'o'
- one character key guess rebindings can give back empty string
when looking for the prefix and it isn't empty, then guess the rebindings --
this fix lets the check not pass and return `'(nil nil)`, allowing the
`(remove-if #'null)` to actually work.
- correcting magit staging when using visual line
