Am very old version of Bw put ctrl enter hint text right above the send button but a later design by nostr:npub1r0rs5q2gk0e3dk3nlc7gnu378ec6cnlenqp8a3cjhyzu6f8k5sgs4sq9ac removed the hint. We planned to add customizable hot key map but never had time to do it.
The idea is to have something like ctrl+h to pop up a help menu and users can see all sorts of guidance there.
Once we finish group chat, will visit back the UX issues.
