Quick answers
What is the ping key in Apex Legends?
Mouse 3 (the scroll-wheel click) on PC and R1/RB on controller. Tap to ping a location or item, hold for the wheel, double-tap to mark an enemy.
How do I heal quickly?
Press 4 for a health item and 5 for a shield item, or hold 4 for the wheel and pick the exact consumable. Healing cancels if you switch weapons.
How do I use my ultimate?
Z on keyboard, both bumpers together on controller. The HUD shows the charge percentage next to the ability icon.
Can I toggle crouch instead of holding it?
Yes. C toggles and Left Ctrl holds by default, so both are available; many players rebind hold-crouch to a mouse side button for slides.
How do I change fire mode?
Press B with a weapon that supports it, such as the Hemlok or Prowler; the ammo counter shows the current mode.
How do I set crouch to toggle in Apex Legends?
You do not — Apex has no toggle switch. Crouch (Hold) and Crouch (Toggle) are two separate actions in the keybind list and the defaults bind both, to Left Ctrl and C. Keep both, or unbind the one you do not want.
What deadzone should I use in Apex Legends?
The smallest your sticks allow without drifting on their own, which for most controllers is Small. A large deadzone does not fix drift, it hides it and takes your fine aim with it.
