Cycling through attack modifiers in Dota 2

I understand that attack modifiers do not stack with each other. And I also want to know how multiple picking up more than one attack modifier changes behaviour in Dota 2.

In HoN, you can cycle through each modifier by assigning a single shortcut key. Is it possible to do the same in Dota 2? If so, please explain to me how it is done.

Solution 1:

Regarding items specifically, the oldest has the priority, so if you want to "toggle" Unique Attack Modifiers, you have to drop all your UAM items and pick first the one that has the UAM you want to use.
