Feature request: ^C & ^Z key bindings for BASH SIGINT & SIGTSTP; F5 alias to ^R

[iconoclasthero]

Current:

^C: refers user to ^Q
^Z: no response
F5: no response

Desired:

Control-C:

I'd like to be able to use ^C for SIGINT (instead of ^Q) so that I can continue to use the same keybinding for quitting as 99% of other applications. I'm not sure if this is a Python thing or not because I notice that e.g., pulsemixer has an issue with ^C to quit, but I assume that just needs to handle the error instead of displaying it on the CLI. (The pulsemixer traceback File "~/.local/bin/pulsemixer", line 1243, in <lambda> signal.signal(signal.SIGINT, lambda s, f: self.terminate()) strongly suggests that signal.SIGINT can be used in Python.)

Control-Z:

I'd like to be able to use ^Z to suspend/SIGTSTP frogmouth, again like most other application. Using pulsemixer as an example, it can be suspended so this is presumably not inherently a limitation of Python.

F5/Control-F5:

Alias to existing ^R binding for people used to using that in browsers.

Rationale:

As in-line above, the standard key to exit a program is ^C not ^Q. It's the standard.
Suspend support should be virtually universal for CLI/TUI applications. E.g., nano's default ^T^Z makes sense only if one wants to use ^Z for undo (instead of the older default of ^U like it was on pine 30+ years ago). But even then, it's still ultimately ^Z.
Since I'm asking anyway, I'll throw in ^F5 because I keep hitting that for refresh instead of ^R.

NB:

I use ^C/^Z because the convention is to use caps, however, I am referring to control-c/z, not control-shift-c/z or control-C/Z, though they should probably be case insensitive.
