Are there keyboard shortcuts for solving?

The solver is built to keep your hands on the keyboard:

• Arrow keys move the cursor around the grid.
• Type a letter to fill the current cell and advance to the next one.
• Backspace clears a cell and steps back.
• Tab jumps to the next clue; the current word stays highlighted so you always know where you are.
• Click the active clue (or the cell you're on) to switch between Across and Down.

Prefer tentative letters? Turn on pencil mode — pencilled-in guesses show lighter and don't count toward completion until you commit to them.
