PS4 L key on the controller?

[Nev Wilton]

Hi, I am new to Playstation. I am playing a game called The Last Of Us. To climb a ladder the game is prompting me to press the L key on the controller. (Not the L1 key) I can't find this key on the controller. Could so

Solved. My Playstation was telling me bullshit.
