Is there some way to use modifier keys for macro's?
I would like to expand, contract and move selections using the same keys with different modifiers but there doesn't seem to be a way to do that.
I have the arrow keys mapped to move commands but now I need to find different keys for expanding/contracting selections. I do press the arrow keys on accident sometimes so ideally I could use them for different things depending on the modifier key.

currently there's no way to this, however it is something we have planned eventually, if you're comfortable feel feee to open a pull request to add this functionality but currently is isn't a priority

There is another mod called "CMDKeybinds", check it out if you want to access modifier keys.
