Allow us to modify to remap the home and end key with Ctrl-a and Ctrl-e (emacs)

As an emacs user, I use Ctrl-a and Ctrl-e all the time while navigating to go to the beginning of the line and the end of the line respectively.

I checked on codemirror and they do have the commands “goLineStart” and “goLineEnd”, but they are not accessible in the obsidian api. Is it possible to have access to them in the hotkeys menu? thx
