There are four main buttons on the PS4 controller: the X button, the Square button, the Triangle button, and the Circle button. The X button is typically used for jumping in games, while the Square button is used for attacking or performing other game-specific actions. The Triangle button is often used for accessing menus, while the Circle button is generally used for cancelling or backing out of menu options. There are also two shoulder buttons on the top of the controller - these are typically used to perform secondary actions or to access additional menus. Finally, there is a touchpad located in the center of the controller which can be used for various purposes depending on the game being played.
