Do you mean with "this behavior" that <C-c> does not trigger InsertLeave? I would want to keep it that way, as this indeed is documented. What I would like to change is that when <C-c> is used in the right-hand side of a mapping, it should also not trigger InsertLeave, but right now it does. That's the complaint of the OP and the inconsistency I meant. Having keys to trigger (<Esc>) and not trigger (<C-c>) InsertLeave is documented and can be helpful. But it's surprising that this special property of <C-c> gets lost when it is part of a mapping. I haven't seen that part documented anywhere yet, and I think it's a side effect of the current implementation, not planned behavior. > I was planning to add a more generic mode-change autocommand. > There is a request for Visual mode enter/leave, for example. > Perhaps triggering whenever the return value of mode() would change > is the most generic solution.

I also remember questions about hooking into entering visual mode, and the current workaround (mapping all v / V / CTRL-V variants) is not very nice. I don't think it would help with OP's mapping problem, though. - -- regards, ingo -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQEcBAEBCAAGBQJb22UEAAoJEA7ziXlAzQ/vfvMIAIFx5YspbuaISQAvL80E+UXW x7cCFpWwjEOgstkKZie9iAlYDsYHoWU/UqFu9bfzSxN4qvDCs8hf5dV59DmQckqm N14pIXyV7qRUsKJ1JQOiyRpx5T9es7Xmt+e6+xmO+T7ga79xSZnBDWDIT+onhqCz DK9jYKXpQy1alR8V/sKeOrQrFT9eYqdmgdwL5KGSwbeDpGv5daU6lH28bSC2SKNt bByISqoAl4kNVvFdOlz/jIrM3GSuwZHMrxuhn+CLvc27EF1EXcsWsXelVuV1a9eL 9jM5HMCM+xDmlhQkTmkTrYHrVqUf0dhByrxVwoVizn5gLdkw7bZzv4id7Qtm8Ss= =kobq -----END PGP SIGNATURE----- -- -- You received this message from the "vim_dev" maillist.
