Keyboard shortcut to switch black/white or foreground/background?

I was watching a video tutorial and the instructor seemed to switch the colour of a layer from white to black with a shortcut, since his cursor did not leave the layer thumbnail section, per below…

enter image description here

Does anyone know which shortcut that would be?

Thanks in advance.


  • Option/Alt-Delete = Fill with foreground color

  • Command/Ctrl-Delete = Fill with background color

  • Command/Ctrl-i = Invert

Chances are the instructor was using one of these shortcuts.
