Quickselect

[Thany]

Newsleecher, a popular(-ish) usenet downloader, has this feature to autoselect posts that are similar but not quite the same in title. An algorithm like that can be applied to filenames as well, and would be useful in folders with large amounts of files.

This is to select files that belong to a set, in a folder with multiple sets. Things like "flower-01.jpg", "flower-02.jpg", "flower-03.jpg" are considered similar. But it's a bit more complicated than just stripping the numbers and matching the rest. It's a good start though. I'm not sure how Newsleecher does it, and it's closed source so we can't look at it, but it works damn well for sure.

Forging a regex, yes, I can do that. But really, that's unrealistic. Just hitting a hotkey is a billion times quicker.

As you said, it can be done with reg-ex.
And such search can be stored and even assigned a hotkey.
