Advertise Hotkeys in ui

[mfbehrens]

Hello there, great fan of this crate :)

When I first started using it, I thought it didn't work, since pressing enter on a device did not connect to the device. After reading the manual, I found out how many features this tui has. I think it is somehow sad that the features do not get advertised in the tui.

I would like to suggest adding hotkeys like here by default. In order to keep the clean and minimalistic look, I would suggest adding a --minimal-flag to the cli. Otherwise, the question mark key could also toggle these hints.

What are your thoughts on that?

I want to write a similarly working and themed tui for the network manager
