Configurable hotkey to switch tabs #4038

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

I'm trying to switch tabs on MacOS with system hotkeys, Cmd-Shift-[ and Cmd-Shift-], and I cannot.

I cannot find the function is custom keybindings.

Describe the solution you'd like I'd like either:

• Make the function hotkey customizable;
• Or, if it's hardcoded, I'd love it to accept the system hotkeys that switch tabs too.

Describe alternatives you've considered

• Opt-Letf/Right works, thought, but it took a while to discover and adjust.
• Ctrl-Tab doesn't switch them, and Cmd-Tab is doing a system global window switch.
