• Initial WASD/arrows select; Initial Space/Enter/Numpad Enter places at the first press; F is an alias
• Mouse/touch: completed click/tap on a legal point places directly; invalid/forbidden points only preview
• Local Black: WASD/Space/F/H; White: arrows/Enter/Numpad Enter/Right Shift
• H plans a hint without placing; U undoes solo; Z zooms; native Place remains available
• Escape closes Help first; Escape pauses/resumes solo/local; P remains Pass; M mutes; F1 opens Help; online Help stays live
• Native focus, IME, modifiers and held keys preserve ordinary behavior; canceled contacts/lifecycle changes never place
• Portrait preferred; landscape supported; controls remain outside the board
• R opens the existing resignation confirmation; Escape cancels it; it never resigns immediately
