After exiting yasnippet snippets that contain one or more tab stops, I often find myself wanting to go back and modify content that I entered at the tab stops. Of course, I can do this using standard movement and editing commands, but it would be much easier if I could simply reactivate, say, the last snippet I inserted and TAB through the fields again.

Another frequent use case is exiting snippets prematurely. I sometimes do this on purpose, but more often than not this happens because I accidentally hit C-g (or some other command that cancels the snippet).

Q: Is there a way to resume or reactivate a snippet after exiting it?

I ran M-x apropos for various combinations of yas/yasnippet and resume/reactivate, but that didn't turn up anything useful.


As @Stefan helpfully points out in the comments, it is possible to call undo to reactivate a snippet. However, this is only useful as long as the current buffer stays unmodified: If I exit a snippet, make some unrelated modifications in other parts of the buffer, and then hit C-/ (undo), Emacs first reverts the most recent changes instead of resuming the snippet, which (in most cases) is not what I want.

    Have you tried to just undo?

  • @Stefan I tried it just now, thanks! It addresses some of my use cases, but unfortunately not all of them (see recent updates to my question).

  • We can wait and see. But I think undo is the best you're gonna get.

As mentioned in my comment, you can undo to reactive a snippet. And if you want to reactivate a yasnippet without first undoing your subsequent changes, you can use undo-in-region, i.e. select a region of text that contains the snippet and do undo.

  • Thanks for upgrading your comment to an answer. Unfortunately, using undo-in-region to reactivate a snippet doesn't work for me. If I (1) expand a snippet, (2) cancel it, (3) insert some text in another part of the buffer, (4) select text containing the snippet, (5) hit C-/, I get "No further undo information for region". Assuming you tested this, could you add a working example to your answer?

  • Hmm... no, I didn't actually test it, I looked at the code instead and it has what is needed for it to work, AFAICT. You should probably report it as a bug.

You can use shift tab to go backward.
