This really helps when selecting pads for pasting but it definitely should be a documented feature! Having zoomed in (by the fairly software-typical method of double clicking on the layout), I was tearing my hair out trying to zoom out again!
On a related note, it would be extremely useful to be able to select individual pads by ‘shift-clicking’ on them. I appreciate that you can select groups of pads by drawing a marquee round them but you can only do it once and it doesn’t allow you to select pads in other parts of the layout. If you could do that it would allow boards to be partially built without covering unused pads with solder.
‘Shift-drag-marquee’ would be even better to select multiple groups of pads. Again this is pretty standard stuff in all CAD software.
