Make the "tab" key work on internal keyboard too

[holzschu]

Currently, pressing the "tab" key on an external keyboard makes auto-complete complete the command, which is great.

Most internal iOS keyboards don't have a tab key, but larger iPads do. It would be great if pressing the "tab" key on the internal keyboard activated auto-complete too.

I've been looking in the docs, but haven't found yet how to register action for specific keys on the internal keyboard.

Pressing the tab button would just insert the first completion in the list 😅
