Drive over a flag to pick it up, and Space to drop it. A superflag on the ground is white and tells you nothing about itself until somebody picks it up.

Mobile On-Screen Controls

• ⤒ — Jump (tap button)
• ● — Fire (tap button)
• ⚑ — Drop Flag (tap button)
• ◎ — Identify (tap button)
• Use on-screen joystick to move/turn

Mouse Steering

• M or the Mouse Steering row — Enable/Disable
• ESC — Leave mouse steering (see Dialogs & Menus)
• Mouse Up/Down — Control Speed
• Mouse Left/Right — Turn Tank
• Targeting Box — Inside the small box the tank holds still; the outer box edge is full turn and full speed, and going further out adds nothing
• The keys still drive: hold a key and it owns that axis, let go and the mouse has it back. Steer with the mouse while holding W, or turn with A/D while the mouse sets the speed.
• Left Click — Shoot, anywhere on screen unless chat is active or the on-screen controls are up
• Right Click — Identify: locks a Guided Missile onto the tank in your sights, and picks the roaming target while observing
• The row is unavailable with no mouse attached, in VR, or while the on-screen controls are up, since those steer instead

Dialogs & Menus

• ESC — Back out one step, and Settings is the last stop: leave chat, leave fullscreen, leave mouse steering, then open Settings. One more press closes it, so pressing ESC once too often costs nothing
• Up/Down — Previous/next control, including from inside a text field
• Left/Right — Change the focused control: move a slider, pick the next choice. In a text field they move the cursor instead
• Tab / Shift+Tab — Previous/next control
• Home / End — First/last control
• Enter or Space — Press the focused control
• This Help panel is read rather than operated, so here the arrows scroll it and only Left/Right move focus

Chat & Misc

• Enter — Send Chat (or click the Send button again)
• ESC — Exit Chat Input
