Layers shortcuts

Note: when I write “current layer”, it often applies to a selection of layers.

Add paint layer: Ins.

Add vector layer: : S-Ins.

Delete current layer: S-DEL.

Duplicate current layer: C-J.

Show layer properties: F3.

Select next layer: PageDown.

Select previous layer: PageUp.

Go to first layer: Home.

Go to last layer: End.

Activate/Select layers in active Layers dock: Arrows keys or S- arrows.

Move current layer down: C-PageDown.

Move current layer up: C-PageUp.

Move the current layer, or selected layers, into a group. If all layers of a group are selected, the group disappears: C-G.

TODO: not working? Move the current layer out and above the current group: C-M-G

Merge current layer on layer below (in list), which keeps its name: C-E. Useful after pasting, when you don’t want to keep too many layers. Warning! Destructive, don’t do it by mistake. But of course, C-Z (undo) fixes that, if you notice what you have done… If the layer below is a group of layer, the group and the merged layer are flattened (making only one layer). If the layer is the last of its group, it does nothing.

Filters shortcuts (image adjustments)

Hue / Saturation / Lightness filter: C-U. Move Saturation to zero to get gray-level image.

Level filter: C-L allows increasing contrast (move side arrows toward middle).

Select some blending mode (part of hotkey): M-S-.... M-S-N (normal), M-S-O (overlay), M-S-C (color), etc.
