Make Neovim receive Ctrl-Space

[npertschy]

Hey folks,

I am a Neovim user. For triggering the autocompletion menu, I like to use Ctrl-Space, which is known to be somewhat of a problem within terminal apps.
Currently, I am mainly using WezTerm and in order to make this shortcut working there, I needed to do something like this

{ key = " ", mods = "CTRL", action = act.SendKey({ key = " ", mods = "CTRL" }) },

Sadly, I wasn't able to enable this shortcut in Rio. I tried the following ideas:
{ key = "space", with = "control", action = "None" }, { key = "space", with = "control", text = "\u0000" },
or only
{ key = "space", with = "control", text = "\u0000" },
or
{ key = "space", with = "control", bytes = [ 0x00] },
or
{ key = "space", with = "control", bytes = [ 0 ] },

Does anyone already solved this problem or has any ideas on this? I really would appreciate it?

Thanks in advance!
