Interaction
From WikiRaider
Interact is a new command in Tomb Raider Legend, Tomb Raider Anniversary and Tomb Raider Underworld. It replaced Action.
Interact is used for various actions such as kicking, moving or picking up objects, for speeding up other actions like climbing, shimmying, diving... and more. Occasionally Lara is about to lose her grip when e.g. hanging on a ledge. To prevent her from falling, the player must use Interact to perform a saving grab.
A special icon appears on the screen, when Interact should be used. This helping feature can be turned off in the game menu.
