There's two ways to get no cooldown shouts. Type "tgm" in the console (PC only) to enable God Mode. Or, if you just want permanent unlimited shout cheese, hack in an item with two Fortify Shout 20% enchantments.

The code for Ancient Nordic Boots of Shouting is "playerenchantobject 56a9d 8850d 8850d"

I'd love to see others' combo vids!

Both are impossible with regular items... what's the point?

Alternatively you can modify the variable that controls shout cooldowns to zero.
