Copy/Paste not working in inputBox input line

[unxed]

You have to create statusbar "listening" for Ctrl/Shift+Ins/Del to generate cmCopy, cmPaste, cmCut commands.

Expected behavior: clipboard manipulations work in inputBox out of the box without processing key combinations manually.

Example below, see !!! comment

Hi @unxed!

I agree that it is annoying not to have this working out-of-the-box, even though I tried to document this behaviour. However, an out-of-the-box solution would require hardcoding specific keyboard shortcuts for these commands, which I don't think is a good idea either.

It is for this reason that the sample applications which allow interacting with the clipboard (tvdemo, tvedit, tvforms) already contain code like the one you shared. Those are the same examples which I would expect most people to look at. I wonder if there are other places where adding these explanations would be helpful.
