Help Please - PSE 21 shortcut needed

[slfam]

I cannot for the life of me remember what shortcut I use to get rid of all of the overhanging papers and elements. I know if I get rid of the excess overhanging the edges of my layouts it will make the file smaller and take up less storage room, but I can't remember what it is.

I'm not sure if this is the right answer for PSE, but you could just open the crop tool & crop the 12x12 then flatten & save?

I don't have PSE 21, but this might work for you if you want to keep your PSD/TIF with layers.

First, make sure you don't have any smart objects. This won't work if you haven't rasterized them. You can select every layer in your layers panel and then right click and choose RASTERIZE LAYERS.

Second, click anywhere on the layout canvas and press CTRL+A. This will select all the layers.

Third, go to the toolbar at the top and choose IMAGE>CROP. You won't see any visible change at this point. PRESS CTRL+D to remove the marching ants around the canvas.

Fourth, you can go to one of the layers that you know was outside the canvas and you should see that the extra pixels are now gone.

I know that's not one shortcut but a series of steps. Maybe someone will jump in that knows PSE better.
