Tap any box and type — it saves as you go (per date, on this machine; EXPORT/IMPORT moves a day as a .json file). TAB walks every box in order · ENTER drops down the matrix column, or jumps to the next scripted play (and adds one off the last row). TEAM ⇉ copies the first cell across. Script calls are engine-checked (⚠ = doesn't resolve; click to open on the whiteboard). Period & personnel names you type are remembered and suggested next time.
