Copy and paste values without clicking Blender supports copying values (even colours) without you having to click in the entry field, select all, copy it... Just hover the mouse over a value and press CTRL+C, go to the entry field (the box where you type stuff, if you didn't know) that you intend to paste this value, hover over that and press CTRL+V It's there! Same procedure for copying colours- in fact, even easier, colours can be dragged from one spot to another to copy their values
