I cannot recall a single mention of Alt-clicking on the eyeball to "see" that layer, nor any of the Ctrl-Clicks or Alt-Clicks on the various mask and image icons. I will go looking for such mentions now and will probably find them many places now.
I got all of that information from the Photoshop manual. Whenever Adobe describes a function, they describe every way of doing it including all of the funky key combinations.
Just read the chapters on Selecting and Layers and you will know everything you need about this stuff. It's a good read! I highly recommend it!
Another hint: ANYWHERE you use a mouse click, also try out alt-click, ctrl-click, atl-ctrl-click, shift-click, etc... to see if anything interesting happens. Eg., if you hold the alt key while in a filter or adjustment dialog, the "cancel" button changes to the "reset" button.
