Global (multi-mode) key bindings?

[edrozenberg]

For certain keybindings it would be nice to define them once and have them work in any mode. I searched and didn't find any relevant issue or discussion about this.

For ex.:

S-home = "goto_file_start"
S-end  = "goto_last_line"

I would like these "Shift+Home/End" bindings to work in any mode. Currently I have to define the same bindings in 3 modes in the helix config.toml:

[keys.normal]
<the same bindings>

[keys.insert]
<the same bindings>

[keys.select]
<the same bindings>

Maybe there could be a [keys] or [keys.global] section, where anything defined applies to all modes.

It would help remove many dozens of redundant lines from my config, remove the need to copy/paste changes multiple times to several modes, and remove the chance of errors when copy/pasting or bindings getting out-of-sync between modes.
