ctrl+enter, a bit werid for me too

Am very old version of Bw put ctrl enter hint text right above the send button but a later design by @HaloKat 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.
