An email I was editing vanished I pressed what I thought was Shift+Return, it's not found in any folder anywhere in Thunderbird - can I find & retrieve it?

I clicked reply to an email and during message composition I used Shift+Return and then the message vanished, it's not in any folder in Thunderbird, no search for any keywords in it finds it's whereabouts - any pointers?

Chosen solution

I solved it using the answer about offline mode & the local folder on, https://support.mozilla.org/en-US/questions/1111844

It appears that something like Shift+Return [line break], maybe with +Ctrl, etc., sends the message - the weird thing is that if I'd clicked send, it would have immediately gone as I am online, so the key command must also treat it as offline until a send/receive operation...

Still haven't figure out what happened exactly, but got the message back to continue editing :)

[Obviously I'm considering I may have pressed something else near to the left shift & return keys, but nothing I can think of would have this behaviour in any event - it would at least be in deleted items, it's like the message was aborted and any autosaved draft deleted and the deleted items folder emptied, which it hasn't been and other stuff predates the message I was writing]
