The issue remains: "-" breaks double clicking to select the full string, which means you'll have to manually select all the characters before copying. Same thing happens with UUIDs: using double clicking, you can only select one block at a time.

This isn't a major issue, which means there's no easy answer and it generally comes down to preference if this is a requirement or not.

Double-clicking foo-bar_baz in GNOME Terminal selects the entire string. Anyway, this is something that is user-configurable surely?

Very few apps are that user friendly, besides your terminal isn't either since whether you want to select the entire string or not depends on its type

It is in many terminals (I think it is in gnome-terminal) but not in major browsers and a lot of other software.

In XTerm it only selects the entire string with this in `~/.Xdefaults`:

  UXTerm*charClass: 33:48,36-47:48,58-59:48,61:48,63-64:48,95:48,126:48

There is also `UXTerm*on2Clicks` and `UXTerm*on3Clicks`.

FWIW, browser only selects either `foo` or `bar_baz`, but not the whole `foo-bar_baz`.
