tmux is a very nice potential replacement for GNU Screen.
It has one accessibility issue: It uses a fake cursor when editing
its own internal command prompt. Apparently, there is no option to
change this. I have checked the code, and it appears the key phrase to
grep for is "Apply fake cursor.".
I am wondering if anyone else has already noticed this problem, and
maybe developed their own private workaround?
If no, it seems worthwhile to work out a patch for tmux to optionally
support a real cursor for editing command prompt input.
I am looking into this right now. If someone reading this is familiar
with the tmux code base I would be grateful for advice. It shouldn't be
more then a few lines here and there.
