Make a little trouble.

Click a part to tune it, or drag across empty space to select multiple pieces. Shift-click adds or removes a piece.

Cmd/Ctrl C copies and Cmd/Ctrl V pastes. M mirror-copies across the map centerline. Drag selected pieces to move together. Arrow keys nudge; Shift moves farther. Drag any corner handle to resize a single piece. Terrain and laser beams also have a circular rotation handle; hold Shift for 15° steps. Spawn markers stay fixed-size.

Option/Alt H centers left-to-right; Option/Alt V centers top-to-bottom. Shift-drag locks one axis. Option/Alt-drag snaps to the arena centerlines. Bold horizontal lines mark floor tops at 100 px steps by default. Hold Control while dragging or placing to snap to them, even with Snap off. Select an existing floor and use “Use as floor reference” to line up the guides. Control takes priority over Option/Alt; add Shift to stay on one axis. Scroll to zoom; Space-drag pans.
