Hi All,
I just came across this list yesterday and am glad to see that screen
is still alive and kicking. It's one of those programs I can't
imagine living without.
Anyway, here's a patch I updated recently for version 4.0.2: it adds
two features I use alot. The first I call "toggle" (^aT). Oftentimes
I do many screen commands in a row like creating five or six new
windows. I do ^aT, then c c c c c (to create five more windows).
When I want to cycle through them, I hit the space bar. Or if I want
to go back n forth between windows, then n and p. All this to avoid
hitting ^a every time I want to do a command. When I'm done and want
to return to normal mode, I hit T to turn it off.
The second jumps to the last window in the list (^a$) - like vi's 0 to
go to the front of the line, $ to go to the end.
It also adds an extra check for the -h option - makes sure you can't
pass a non-digit as an argument.
If anyone's interested in the patch, I'll clean it up.

Sincerely,
Matt Dunford
