[Bug 39180] UI: missing visual cursor-hint when a cell is draggable.

Hi team,

I'm forwarding this bug for discussion and action. Currently, in Calc,
when you press Shift and click a cell or cell range, you can then drag
and drop it to a new location in the sheet. Great feature, but it's
not documented anywhere I could find it.

Notably, I find no documentation of this behavior in the Calc guide or
Getting Started guide or in the online help. That's something we'd
really need to fix.

Comments? Volunteers? (I'm monitoring this bug myself so we don't lose
sight of it.)
