Knowing non-algol languages won't make editor actions any less useful for algol-like. If anything, it'll just make you pretend that you don't need such and as such will end up less productive than you could be.

And editor actions can be useful for any language which either allow you to edit things, or has more than one way to do the same thing (among a bunch of other things), which includes basically everything. Of course editor functionality isn't a thing that'd be 100% beneficial 100% of the time, but it's plenty above 0% if you don't purposefully ignore it.
