In previous versions, if I wanted to submit chat a second time (e.g. the first time it had been walloped off the screen too quickly by a sudden splurge of automatic messages or a couple of massive gestures), all I had to do was press ctrl-up arrow and my previous chat appeared in the chat line ready to submit if i wanted - or I could keep pressing it and run back through my recent chat to retrieve an earlier line of chat.
Has this gone (if so why?), or is it still there but now a different key combo?
