feature request: a few QoL improvements

[chris-kruining]

Hey, been using crush for about a week and mostly loving it. there are some point that do annoy me though, so I wanted to share them in hopes of having a conversation about them (or best case scenario just having them fixed I suppose :P)

this is all about the prompt text box:

• I would like a way to 'cancel'/clear what I've typed so far, but have not yet sent. Since crush is a TUI and I am used to do clearing/canceling with ctrl+c on the terminal that would be my preferred shortcut for this (perhaps ctrl+c first clears the prompt box, and if that is empty then it'll behave the same as it currently does?)
• ctrl + arrows breaks quite often (sometimes just all arrows self break as well). I believe this could just be a bug. When I just started up crush it seems to work fine, but after using crush for a while it stops working. A guess I have due to this pattern is that I have done some kind of interaction, somewhere in the UI, that leaves the prompt box in an "erroneous" state.
• I would reaaaaaaally like it if the prompt box would support shift+enter/return for inserting new lines. My brain is hardwired on that key combination and I am really struggling with switchig to ctrl+j in order to do this. And I -likely naively- don't see any blockers for why shift+enter shoudln't work

Again, really loving crush, great work!
Would love to hear your thoughts.
