It's the second column of upgrades for the Titan abilities, on either the Striker or Defender subclass.

Lift: Jump and then press jump again while in the air to activate Lift.

It has three upgrades to it, for both subclasses:
 * Increased Height: Upgrades Lift to travel to greater heights.
 * Increased Control: Upgrades Lift for better directional control while in the air.
 * Catapult: Upgrades Lift to provide a strong initial burst of momentum.

Something that isn't detailed is, with the Titan, you can cancel Lift if you only want to travel a certain distance. Just press jump a third time to abort the Lift and drop down at your current location. For example, if you only want to jump up on a ledge that's higher than your basic jump will go, press jump once to jump, a second time to activate Lift, then when you're high enough to get on the ledge, press jump a third time to abort the rest of the Lift. It's useful for getting into a door or window that's above you, without bonking your noggin on the top of the opening, causing you to fall back down.
