I recently discovered KLayout and it seems very fast and useful.
I usually find myself in the position of selecting a shape, pressing 'Q' for the Object Properties, then reading the Layer nr. (ex. 33/0) , then going in Layers list, selecting the "33/0" layer, and then I change the color or the stipple in order to view all shapes on that layer.
Is there any shortcut/hotkey to directly select one leyer starting from the selected shape ? In Cadence - virtuoso this function is named: Tap.
