Sorry, that was the wrong selection for the Layers Panel.
Mnemonic: Think of six as a Demonic number, and Hercules
transcending the Layers of Hell.
Cmd 3, 6, 7, & 9 do not result in 300%, 600%,
700%, & 900% Magnification. Therefore think of Cmd 5, 1, 2, 4, &
8 resulting in 50%, 100%, 200%, 400%, & 800%, because they are higher
magnifications by TWO.
