No, because screen is not an xterm.

There doesn't appear to be a standard for mouse escape sequences. And termcap/terminfo is too limited for the features of modern terminal emulaters. That means the only choice for Vim is to implement mouse support for each terminal separately. If screen uses the same codes as xterm then this should be relatively simple. It's about time termcap/terminfo gets updated to support the features we need, instead of hacking solutions in all programs. I'm afraid I don't have time for this (the original development of termcap was closely related to the early development of vi). -- >From "know your smileys": :-)-O Smiling doctor with stethoscope /// Bram Moolenaar -- [EMAIL PROTECTED] -- http://www.Moolenaar.net \\\ /// sponsor Vim, vote for features -- http://www.Vim.org/sponsor/ \\\ \\\ download, build and distribute -- http://www.A-A-P.org /// \\\ help me help AIDS victims -- http://ICCF-Holland.org ///
