Single hot corner, multiple options?

Question

Hi guys,
I recently updated my iMac from app store's downloadable Mountain Lion (10.8.2).
And I bought a Mac Pocket Book for learning about this new OS.
Here's the thing confused me a lot.
The author said these:
Use the drop-down menus to set options for any corner you want. After that, when you move your mouse to that corner, your Mac fires up the screensaver (or does what you told it to—put the display to sleep, launch Mission Control, or whatever). The only downside of setting hot corners is that Apple gives you eight options for each corner, so unless you want to use a modifier key with the corner, you don’t have enough corners to use all the options.
By using modifier keys (you can choose from Shift, ⌘, Option, and Control), you can get a single corner to do many different things. To add a modifier key to a hot corner, hold down the modifier key while you select what you want the hot corner to do from the Active Screen Corners window’s menus. Using modifiers with hot corners not only gives you extra flexibility, but it also prevents you from accidentally invoking the hot corner action when you’re mousing around.
But I cannot set a single corner with multiple options! Could you guys can do that???

Answer 1

I'm with you. I can get 10.8.2 to require a specific modifier key in a corner, but I cannot get multiple modifier keys to do different things in the same corner.
However, the author is right that on the last point. It can help prevent unintended activation.
