If your goal is to keep track of what text is added and deleted, the netbeans interface is indeed the way to do this. It's not particulary easy to use, but it has the functionality. The autocommands will only trigger before/after a change, they won't have a way to know exactly what was inserted or deleted. It's unlikely that these autocommands will be added in the near future, because it will be very tough to handle side effects (e.g. when an autocommand for text being inserted then changes text). -- 'Psychologist' -- Someone who looks at everyone else when an attractive woman enters the room. /// Bram Moolenaar -- b...@moolenaar.net -- 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 /// -- You received this message from the "vim_use" maillist.
