Issue

Hello! In my Vim configuration I'm using this kind of mapping to CTRL + / (slash which is on the left of right shift button:

map <C-_> <leader>c<Space>

It works in other terminals (tested in xfce terminal, guake, konsole, rxvt, gnome-terminal) but not in Hyper.

Just ran into this issue myself. Any movement here? I'm happy to provide logs etc. if that will help.
