Display Active Modifier-Key Command on Screen when holding Control, Shift, or Alt
When holding down any combination of Ctrl, Shift, or Alt, Illustrator should display on-screen text indicating which command is being invoked.
Moving or duplicating artboards requires the artboard toolbar to be selected, and then Shift+Ctrl+Alt keys to be held at once in order to drag a duplicate artboard parallel to the original. A simple on-screen text saying "Drag artboard, Drag parallel, Drag with Contents" or similar would help users intuitively understand which hot‑key action is being triggered, especially when working with multiple modifier keys where memorization can be challenging.
This can be used not just for artboard commands, but all six (!) different paste commands, too.
