see Toggle between WYSIWIG/Markdown editor mode with keyboard shortcut:
I want to pick up the original feature request for a keyboard shortcut to toggle WYSIWYG editor and markdown editor.
In (closed) topic, the discussion drifted from the primary question to CTRL L which toggles layout.
I went through Tools → Options → Keyboard Shortcuts but »Toggle Edit-Mode« is missing.
Especially for bidirectional operations between Joplin and word processors, it would be very useful to have a fast toggle shortcut for cut/paste operations. So that the advantages of the respective editors can be used and conveniently connected depending on the requirements.
My proposal would be Shift Alt E because Ctrl E toggles (in standard configuration) to external editing.
