IDE - move selction by mouse

[Perkin]

Hi, done a search but can't find this, so if it has been requested before, apologies in advance.

When a selection of text is moved with the mouse, it can be moved to anywhere within the current code display area.
I would like to be able move the selection out of the current area, and would like the display to scroll if needed to get where I want to be.
Or if while moving the selection, pressing 'PageUp' or 'PageDown' or cursors the code area should scroll.

Any chance of this?
