The default control scheme for Yooka-Laylee and the Impossible Lair for PC is:
Up, Down, Left, Right OR WSAD – Directional controls
Space – Jump, also talk to people, select options in the menu (works as the ‘A’ button)
Anomoly: The ‘X’ button can also be used to jump but loses function entirely when around anyone you can talk to and CANNOT be used to talk to a person.
Esc – Works as the ‘B’ Button, cancels out of menus, and pauses the game. Minor annoyance when you pause the game and also exit from a menu/conversation.
Tab – Zooms into a third-person ‘shooter’ angle, used for aiming Yooka for shooting items later in the game.
C – Uses Yooka’s tongue. Initially grabs hold of butterflies but will also grab hold of other things later in the game after learning proper moves from Trowzer.
Z – Your attack button. Use it to spin into enemies or attack in the air.
Shift – Used to duck. It Will initially not be useful as keyboard players cannot ‘sneak,’ but comes into play later with moves learned by Trowzer (see advanced controls section for more)
Q – Rotate Camera Left
E – Rotate Camera Right
Spacebar – swim-up (towards the surface)
Ctrl – swim down (towards the ground)
Shift – Rolls Yooka into a ball so that you can roll around. It is also used to create a bubble underwater.
Space + Ctrl – Your slam attack. He jumps into the air, then slams Yooka into the ground.
Alt – Uses Laylee’s Echolocation ability.
Ctrl + Alt – Uses Laylee’s super-echolocation.
Ctrl + Right Mouse button – Uses Yooka’s invisibility.
Ctrl + Left Mouse button – Allows you to fly. Oddly, using ‘Jump’ (space) allows you to gain height.
Shift + Alt – The final move allows you to roll around with a sonar shield.
