Hello,
The new Code Mirror 6 (CM6) plugin is providing a useful “Zen mode”.
(https://deploy-preview-9556--tiddlywiki-previews.netlify.app/)
Would it be possible to launch a save and continue editing action with a shortcut inside CM6 Zen Mode?
Some plugins address more or less this action with the classical editor (I was not able to make them work with a keyboard shortcut):
BR,
Eskha
