About the future editor
Is your feature request related to a problem? Please describe.
While the editor is the best i've seen, it is annoying that you need to keep another page open to look up the simple commands that you might have forgotten.

Describe the solution you'd like
This other editor has a "Cheatsheet" sidebar, that just list the most common commands with a short example.

Describe alternatives you've considered
The alternative is always to just use the wiki page i guess.
