Current behaviour

Currently, pressing Ctrl-Enter (Cmd+Enter on MacOS) in the beta and legacy markdown editors does nothing. In VSCode and with the default CodeMirror setup, it inserts a new line below the current.

Expected behaviour

Pressing Ctrl-Enter should have behavior consistent with VSCode and the CodeMirror 6 defaults.

I am trying to work on it but need a bit assistance in finding where to add the changes. I found this article https://www.electronjs.org/docs/latest/tutorial/keyboard-shortcuts that mentions adding the shortcuts in Electron JS using accelerator but I want to know where should I implement these changes as we have multiple directories in note body i.e. CodeMirror, PlainEditor, TinyMCE.

If someone can point me to the relevant code it'll help a lot.

I don't think this has anything to do with electron shortcuts. It should be specific to CodeMirror (version 6, since it mentions beta editor, I believe)
