@b0rk Not the same combination, but I've used ^[ as escape when I couldn't quickly or easily find a way to press the key itself. You may have already come across it, but such control character combinations feel slightly more reasonable to me when looking at a 4-column ASCII table showing all of them: https://garbagecollected.org/2017/01/31/four-column-ascii/
[Edit: Ooh, this view of the table (from elsewhere in the tree of replies) looks interesting as well: https://mastodon.social/@Ange/112752251139584718]
