Hi, thanks for a great library! I stumbled into something that looks like a bug.
I declared custom “Ctrl-Space” key binding and codemirror never runs it. I also noticed codemirror/autocomplete has startCompletion command, it also does not work.
I did some debugging and I found that binding is empty when Ctrl-Space shortcut is empty. Also, Ctrl-Space is stored as Ctrl- , and user input is interpreted as Ctrl-Control for some reason.
The basic setup binds ctrl-space to startCompletion with high precedence, so that is capturing that key. You’ll have to either do your own configuration to change that, or make sure your keymap has higher precedence.
