Nudge a number or date from the keyboard
Press ⌃⌥↑ or ⌃⌥↓ to nudge the active cell. Numbers move by one, dates by a day and percentages by a percentage point. Add Shift for a larger step. Hold the key to keep adjusting, then press ⌘Z to undo the full adjustment.
Empty sheets show one first-run hint at a time. Start typing, open the command palette or use Escape to hide Scratch. Each hint retires after you use it.
