SHORTCUTS
OpenFront Shortcuts
Every default keyboard shortcut, mouse control, and build hotkey in OpenFront.io, grouped for fast lookup. Since v24 most action bindings can be remapped (and some unbound) in Settings → Keybindings; v33.5 still has the fixed exceptions below. On macOS, read Ctrl as Cmd.
Applies to v33.5 · verified August 16, 2026. Double-press the same build key to toggle x1 / x5 for an existing upgrade or Atom Bomb. The radial menu offers structure x1/x5/x10/xMax and Atom Bomb x1/x2/x5/xMax batches; Gold and loaded Silo tubes cap xMax.
New here? The fastest win is the build number keys — tap 8 once for one Atom Bomb or twice for x5, then left-click. Same-Silo bombs leave one tick apart; separate ready Silos can fire together. For the strategy behind these keys, read the in-depth Hotkeys guide →Build & unit number keys
Tap once for x1. Tap the same key again to toggle x5 for an existing structure upgrade or Atom Bomb; new structures, Hydrogen Bombs, and MIRVs stay x1.
