Just an “enter” is most commonly used by other apps, so using “enter”, there’s no need for “hints”. The hint menu can show other shortcuts, but “enter” to send message is most intuitive.
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.
Discussion
Some apps let you choose between enter or enter ctrl for send and new line respectively. Therefore a help menu is necessary
