Learn a handy keyboard shortcut to merge two layers in Photoshop
One simple trick but one that comes in handy constantly for me is merging two layers into one in Photoshop. This trick can save your life with so many Photoshop projects that require two images to be merged to a single layer.
Now your layers are merged.
Something to keep in mind is the new layer when it does merge will take the name of the layer on the top.
