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

I think it would be sufficient to just print hotkeys in the --help section, which is currently useless since it prints only:

Options:
  -h, --help     Print help
  -V, --version  Print version
