thanks - will check. I would have noticed this, but rxvt + screen on
my Debian/testing doesn't work together. The underlying problem is that
some keys (home/end, etc) are #define'd in rxvt's sources and won't
necessarily match on other systems.
Interesting. I use
rxvt-xpm -geometry 99x35 -bg black -fg grey67 -fn
-misc-fixed-medium-r-normal-*-*-200-*-*-c-*-iso8859-15 -sr -sl 5000 -ls
and never had any problems with screen (on a remote server connected via
ssh) until now.
If you tell me, how to display the different codes Pos1 and End produce
with TERM=screen and TERM=screen.rxvt, I may me able to aid your debugging
efforts.
I spent some time last night investigating it. The underlying issue is
that screen does more than would be apparent from this paragraph:
When screen tries to figure out a terminal name for
itself, it first looks for an entry named "screen.<term>",
where <term> is the contents of your $TERM variable. If
no such entry exists, screen tries "screen" (or "screen-w"
if the terminal is wide (132 cols or more)). If even this
entry cannot be found, "vt100" is used as a substitute.
I'd already noticed that it did something odd with home/end keys, but
when making screen.rxvt saw that it "ignored" the values for kf1-kf4
in screen.rxvt -- so I set values to match what screen actually passed.
screen sees the key-definitions in "screen.<term>" and translates them to
the corresponding strings in "screen", rather than passing them through
unchanged. So it saw that kfnd was defined for \E[1~ in "screen.rxvt",
it mapped that to the "screen" kfnd.
Here's an improved definition:
screen+fkeys|function-keys according to screen,
kend=\E[4~, kf1=\EOP, kf2=\EOQ, kf3=\EOR, kf4=\EOS, kfnd@,
khome=\E[1~, kslt@,
screen.rxvt|screen in rxvt,
bw,
cvvis@, flash@, kcub1=\EOD, kcud1=\EOB, kcuf1=\EOC,
kcuu1=\EOA, use=screen+fkeys, use=vt100+enq,
use=rxvt+pcfkeys, use=vt220+keypad, use=screen,
