One of TUI advantages over GUIs (including modern web sites) - all text can be selected/copied (you may need to use modifies in some TUI). It's a bit frustrating when GUI shows text but I cannot select and copy it.
It's not only about buttons. A web-app of trading platform I use doesn't allow to copy-paste a fund name (both in web and in the mobile app). I don't think they disallow this intentionally, likely an artefact of GUI framework they use.
What if it just popped on top in a dialog to the content you were about to select?
