Forums Feature Suggestions ON COPY event

When a user highlights a bit of text in a channel, it is automatically copied to the clipboard. I would like to suggest an ON COPY event, which will be called when the user hightlights/copies some text either in a channel, window, or anything else where the highlight/copy feature applies.
As far as I am aware, it does not work for Dialog boxes. I think it may also be worth adding it for Dialog boxes? perhaps. So for instance, when someone selects some text in an editbox within a dialog box, that text is also copied to clipboard.

If it's not possible yet (im not sure),also make it so the script can get whatever text is currently on the clipboard. I want this event so that when someone highlights text and copies it, a separate window appears which displays the text which was copied.

Other possible names for the new event: ON SELECT, ON HIGHLIGHT
