Add "volup key" to new extra keys panel

[memeplex]

I was surprised about the keyboard extension not including a modifier capable of doing the same than Volume Up does in combination with other keys.

@memeplex, has this happened?

It amazes me that this is still open. I'd love to have a shortcut to open a new terminal but I don't think this is possible—CTRL ALT c isn't caught by Termux, it is passed to the tetminal session.

All the volume key combos can already be directly added to extra keys as separate keys (except last 3 for volume and extra keys itself), so don't think this is necessary.
