Clickable shortcuts in TUI

[xsebek]

Is your feature request related to a problem? Please describe.

I would like to click the function shortcuts (help, robots, ...) and the shortcuts between World and REPL (unpause, step,...) with the mouse. This way I would not have to use a keyboard for every functionality.

Describe the solution you'd like
Make the widgets clickable with name like UIShortcut SwarmEvent, so that the event can be handled on click.

It's going to take me some time to come up to speed on issue #1141 and in the interim, if it's still up for grabs, I'd like to work on this issue.
