Shortcut to Lock/Unlock

I want to suggest a shortcut to quickly lock/unlock pages. Other tools like Obsidian or Frontify switch between the edit and view mode with CMD+E/ STRG+E which is super handy.

I find myself constantly pressing this shortcut in locked Coda pages – of course without a result. Could something like this be implemented?

CMD+L sets the focus to the address bar, so that might not be the best choice. Not sure if CMD+E has other purposes.
