Getting closer to the editing workflow I wanted:

1. Press "nnn" to create a new page.
2. Fill the required fields, press enter to submit the form.
3. You are redirected to the newly created page.
4. Press "eee" to edit the currently visited page, do your modifications.

And that's it! Once I combine this with a search, I'll be able to visit and edit any page very fast. No back-office required!

I'll have to replace the keyboard shortcuts with something else on mobile. Got a few esoteric ideas, but dunno if I'll take the time to explore them.
