quick snippet edit

[vim]

it would be nice if i could edit snippets quickly, either from the snippet menu or with a special key, like shift+tab (like when you enter the snippet key strokes but instead of pressing tab, pressing shift+tab)

what do you say?

Another option would be to provide API access to the commands used in the undo buffer history - this would allow an edit-last-used-snippet command, which should be a reasonable way to do it.
