Uses of the team portraits in game

Your team portraits on the top left of the screen have a couple useful uses. Some of you may already know them, but this is for those who don't. If you ping on the portrait of say, your mid laner, then whatever you ping will be on them. Also, if any of you have played Shen you know this, if you click ult while on a portrait it'll ult that way. Shen does it to an ally. However a Jinx ult will fire in the direction of your teamate if you do it while your cursor is on a portrait (I've missed many ults because of this, feelsbadman). Just a bit of info for your day if you didn't already know it!
