For all the new people starting out: I was reading a few general and Champion guides here and there and this should definitely perk up your interest in playing better and winning.

[/SPOILER] Here are some interesting shortcuts and tid bits from the game because apparently not many people know these:
Zilean bombs can be placed on stealthed champions and wards; the bombs will remain invisible.
You can see your latency by pressing CTRL+F.
ALT+QWER will self cast any skill on yourself. This is very useful for champions like Nidalee (quickly self casting heal will often save you).
SHIFT+QWER will smart cast any skill right where your pointer is. You can also use shift on your team portrait boxes (on left of screen) to cast on them (doesn't seem useful though).
CTRL+QWER levels up a skill for you, removing the need to click the + box.
Holding down ` will only let you target champions.
You can press 123456 to use any consumable or active item in your inventory. 1 will be the upper left box in your inventory while 6 would be the lowest right box.

An extra tip from me, BUY DEFENSE. Even if you are the carry, you need to buy some defense as soon as someone starts snowballing or if it hits late game. A dead person has a DPS of 0. I just fought a game versus a snowballing Gangplank who had 100% critical chance with an infinity edge and two phantom dancers. As soon as he started snowballing I saved my money and bought a Thornmail. Even with only a Deathcap for AP (as Malzahar) I melted him in a 1v1, leaving with over half my health left.
