The Course overview block can of course be used to filter variously timed courses, not just those "in progress" or (to use a synonym) "current".

Accordingly, I find the use of the word "current" in the string aria:courseactions for blocks/myoverview at least potentially confusing / strange / incongruent.

The illustrating screenshot I provide is from Moodle 4.0.*, but the situation is the same for up to the latest released versions, and probably also 4.4dev.

Not sure what the best solution might be - maybe just the plain "Actions for the course ...."?
