So I'm midway through implmementing it all, and I'm finding that a lot of both meta and alt keys have behaviours that block them from working on my Mac. I know on Linux it probably isn't like that, but a lot of people will have Meta- bindings for some actions in the UI. Would it be a huge issue if it defaulted to CTRL? ATM I'm having issues even recording the value of my meta keypresses as too many of them are default bindings in MacOS.

Edit: Regardless, it is now pushed on GH. Will be included in next version, thank you both for the suggestion!
