Spreadsheet
An Excel-class grid composing 2-D rectangular range selection with in-cell editing. Shift+Arrow extends the selection and Ctrl/Cmd+A selects all; Enter, F2, or a double-click edits the focused cell (Enter commits, Escape cancels), and arrow keys while editing move the caret rather than the selection.
