    Official description of Alt + Delete + Backspace command

    lc55472355 Level 1

      I am searching for an explanation, in Adobe's official Photoshop vocabulary, of what the Alt + Delete + Backspace command does in the following sequence.  I've searched Adobe and the net and cannot find it.  Can anyone give me a reference for this?

       

      • Open a black and white PNG file.
      • Make the foreground color black.
      • In the Channels panel, Ctrl-click on the RGB thumbnail.
      • Select > Inverse.
      • Create a new empty layer.
      • Hold down Alt + Delete and then quickly press the Backspace key.
      • The result is the creation in the empty layer of a transparency of the original file:  white areas are made transparent; grey areas become semi-transparent; pure black areas remain black.
