I routinely disable isearch highlighting when running keyboard macros especially if the file is large or the macro is run repeatedly. (Aidan's patch seems related to that.) Also, if the macro modifies the file, turning off auto-save for large files (or at increasing the auto-save interval) also helps. -- Skip Montanaro http://www.musi-cal.com/ skip(a)pobox.com
