I was expecting the keyboard shortcuts editor to allow me to ADD a shortcut to a command that, by default, comes without a keyboard binding - like e.g. indeed Move Cells Up or Restart kernel and run all cells
I’m still interested to know if there are plans to let people do this without messing with JSON
There is an issue about this tihng here: Semantic commands are missing in shortcut editor (regression) · Issue #13705 · jupyterlab/jupyterlab · GitHub
There is a draft PR:
You are welcome to contribute - we still need to have a way to define a selector in the UI to make it work. Let me now if you need some guidance (but I have very low availability this month).
