I recently watched an online tutorial, and the maker said 'Apply the layer mask'.
Essentially he duplicated a layer, then added a layer mask and made an gradient adjustment on the mask. He then 'applied a layer mask', which deleted the mask. The change he made to the layer had been made permanent, and the mask was removed.
Has anyone any idea how this was achieved? Either by the menu, or a shortcut.
Layer > Layer Mask > Apply
Thank you very much!
