Olipcs is right. Just to clarify, the restriction is that Shift can't be used as a trigger by itself. This restriction has no effect on output. Hotkeys can take any action you like including sending Shift by itself.

I made this restriction to try to prevent certain user errors. I'm planning to remove it before the end of the beta.

Please let me know if Olipc's Y hotkey solves the problem. If so I'll raise "removing the restriction" up higher on the to do list.

(I'm sure you realize Y can be any main key or combination of keys.)
