Re: whats the keyboard short cut to the toggle between alpha channel & the original l
On my system, the default assignment is:
Ctrl + \ to switch from layer contents to the layer mask, and
Ctrl + 2 to switch from the layer mask to the layer contents.
Obviously, you can reassign these if you want. For example, I would love it if the same keystroke would simply toggle between the two, and didn't require a different shortcut for each direction.
