Can't Accept completion if keyboard in floating mode

Edit: I found the actual issue is that the “Accept completion” keyboard suggestion doesn’t appear when my keyboard is in floating mode. This is different from using an unsupported language as I’m on python so it works in docked mode.

I am trying to accept the completions made in line by ghostwriter by pressing tab, but my keyboard (Google Gboard) doesn’t have a tab key.

I need some other onscreen affordance to accept the completions on mobile.

shouldn’t have presumed that it’s the same problem

for now, you could add a tab to your personal dictionary
