Allow ctrl-z to suspend lazygit

[ricardoseriani]

Is your feature request related to a problem? Please describe.
Cannot suspend lazygit using ctrl-z

Describe the solution you'd like
Provide a way to disable the ctrl-z keybinding to Redo, and allow the command to send lazygit to background.

Describe alternatives you've considered
I cannot think of any alternative way to do this, but if there is some, please let me known.

Additional context
The majority of software that run on Linux terminal allow the use of ctrl-z to suspend the current software, allowing to run fg or bg commands to continue the software on foreground or background.

But, currently, the ctrl-z keybinding is tied to Redo.
Even if I try to remap the Redo command using the .config/lazygit/config.yml like the following, I cannot run ctrl-z to suspend lazygit

keybinding:
  universal:
    redo: <c-g>

interesting.

@ricardoseriani for now, I use dislocate -escape '^Z' lazygit for this purpose ¹²

Footnotes

1. dislocate(1) is a old expect script, it just works ↩

2. ^Z is a "ctrl-z character", ascii 0x1A, which can usually be obtained by typing ctrl-v ctrl-z ↩

It is a curious mapping by default, ctrl-z serves as the suspend signal by default in any tty I can recall.
