Hello,
I'm trying to replace rxvt-unicode with termite, and am having trouble with
my mutt bindings.
Termite emulates an RS-232 terminal--a simple (AKA "dumb") ASCII
terminal, whereas rxvt has a more complex interface that allows sending
and receiving a variety of control sequences to represent when someone
has pressed a key with a modifier key (like Alt) and other control
functions.
I guess I'm mostly confused why mutt takes Alt-[a-zA-Z] and Alt-Return
modifiers from termite but doesn't take Alt-[Arrows].
Not sure why you're trying to do this, but I don't think it's going to
work.
I'm trying to switch to a Wayland-native terminal emulator. All the
minimalistic ones (including termite) appear to be VTE-based, and all
appear to have the same input problems as each other.
RS232 terminals, IIRC, at most supported a few basic ANSI control codes
for cursor movement and text formatting.
I have
bind index,pager \e<Up> sidebar-prev
bind index,pager \e<Down> sidebar-next
bind index,pager \e<Return> sidebar-open
which in rxvt-unicode navigates the sidebar with Alt-Up, Alt-Down,
Alt-Return. In termite the sidebar-open binding still works, but neither the
Alt-Up nor the Alt-Down do. The what-key utility gives 'A' and 'B' as the
keypresses associated with them, respectively, but binding 'A' and 'B' to
sidebar-next and -prev don't work.
RS232 terminals can send all of the bytes 0-255, which includes the
control characters from 0-31 (ctrl-A is 1, ctrl-B is 2, etc...) so the
best you're probably going to be able to do here, is identify some
control characters you're not using for something else, and map those
to your sidebar functions. Your options are limited though.
I could be mistaken about all that though--really if there's a mailing
list for termite, that's a better place to ask this question.
Back on urxvt for now, but I'll poke around the termite support. Thanks!
I haven't seen anyone trying to use an RS232 terminal since I had a
9600 baud modem.... that was like 35 years ago. Even minicom supported
vt100 terminal emulation over a serial line...
