feat: change keybinding for remove node from command + backspace

[dionysuzx]

Is your feature request related to a problem? Please describe.
Yes, as a mac user I often use command + backspace to delete the current line.

Describe the solution you'd like
Change from command + backspace to something equally ergonomic. I'm new to the tool, so I would prefer whatever is pragmatic in the context of the other keybindings.

Describe alternatives you've considered
None

Additional context
None
