I've taken a couple of stabs at this, without a great deal of success. The problem is that scrollback in, say, xterm is nonmodal--at any time, you can press Shift-PgUp and go backwards in the terminal's scroll buffer. screen, on the other hand, is modal--you must enter copy mode, *then* go back a page, but once you're in copy mode, PgUp and PgDn work as you'd expect. The closest I've come has been: In .screenrc: bindkey "^[[5;2~" eval "copy" "stuff ^b" In .Xresources: XTerm.VT100.Translations: #override \n\ Shift <Key>Prior:string(0x1b) string("[5;2") This causes xterm to pass the Shift-PgUp through to whatever program is running within (presumably screen)[0], and then screen will catch it, enter copy mode, and go back a page. The problem is that Shift-PgUp will not work a second time, since it will always try to enter copy mode, and screen doesn't like doing that (it displays an error message, which tends to slow things down). Next round I go with this will probably involve trying to have screen rewrite xterm's keybindings when it enters and exits copy mode, which has the problem of synchronization (not sure there's a way to execute a command when screen exits copy mode as a result of an invalid keypress). [0] Note that I've hardcoded the escape sequence instead of just binding it to insert(). That's because I had to hardcode the escape sequence in screen, since there's no termcap entity for Shift-PgUp (as far as I can tell). -- ...computer contrarian of the first order... / http://aperiodic.net/phil/ PGP: 026A27F2 print: D200 5BDB FC4B B24A 9248 9F7A 4322 2D22 026A 27F2 --- -- When the global thermonuclear war comes to deal with the market and art-lovers everywhere, the only things left afterwards will be grass, roaches and sooty IBM buckling spring keyboards. -- Arvid Gidhagen ---- --- -- _______________________________________________ screen-users mailing list [email protected] http://lists.gnu.org/mailman/listinfo/screen-users
