;; This mode allows multiple buffers to be 'locked' so that scrolling
|
|
|
|
;; up or down lines in any buffer causes all the buffers to mirror
|
|
|
|
;; the scrolling. It hooks into the post-command-hook to check for
|
|
|
|
;; potential scrolling commands and if we're locked, mirrors them in all
|
2006-11-24 11:22:05 +00:00
|
|
|
;; windows. This allows us to grab line-at-a-time scrolling as well as
|
1997-04-29 20:55:16 +00:00
|
|
|
;; screen-at-a-time scrolling, and doesn't remap any of the keyboard
|
|
|
|
;; commands to do it.
|
|
|
|
|
1997-04-29 21:06:16 +00:00
|
|
|
;; You can enable and disable this mode with the 'scroll-all-mode' command.
