Capturing messages from ide popups?

OS Windows 10

I'd copy one and put it here if I could for descriptive purposes (ha!)... but I would very much like to be able to at least copy the text that comes up in the hint popups that show up in context in the editor.

I wouldn't be surprised if there were some trick do doing this... ultimately I'd like to be able to easily get a screen capture of just the body of these (so I don't have to manually cut it out of shot), but that bashful little bugger disappears no matter which screen shot option (snip tool, windows native screen shot).

Is this possible? If not how do I open a feature request?
