<C-[> for escape

[goyalyashpal]

hi! thanks a lot for such a wonderful extension.

• many terminals support pressing <C-[> i.e. ctrl-lbracket (square) to perform as escape key.
• and this comes in handy a lot in modal editors (nvim, hx, kak, etc) ...
• as escape island is far away for my fingers to reach while dancing

so, can that be achieved?

• no duplicated found: jj or jk is parallel, <C-v> is tangential
