League-of-legends – hotkey to gain a point in a skill without clicking the icon

There are many good reasons to have a jungler in your team:

• The player that stay solo (top usually) while he's lane partner jungle get more gold and experience.
• The jungler can do or help doing some kills by ganking mid (2vs1) or bottom (3vs2) in any moment.
• Some champions are more efficient in jungling than last-hitting in lane (e.g. Amumu, Rammus, Malphite)
• Best junglers can also take the dragon (190 gold to all team members) early

Each item slot, 1-6, is initially bound to the corresponding number key.

You can rebind this during gameplay if you wish, but I like to simply move activated items into the 2nd slot and hit 2.
