What to use to make simple turfs

[Frychiko]

Ah I meant, click on the layer window and drag a layer down or up, and THEN try to nudge the canvas up or down one pixel, or select another tool by keyboard. (without clicking elsewhere while the layer window has focus).

[Beoran]

Ah, I see. Well, it kind of makes sense, though, that you lose focus, as you're clicking inside another window. It may be better to assign custom keyboard shortcuts for moving the layers and hiding and showing them.
