Arrowsheet, a keyboard-drawn notepad

Field notes

Arrowsheet uses a grid cursor as both pen and insertion point: arrow keys leave square trails, letters place text, and ⌥B turns a traced rectangle into a resizable box. Its documented note-taking grammar includes ⌘V image pasting, ⌥V region movement, folders organized by subject or term, and a whole-sheet view via ⌥0. The page describes the tool as a single HTML file that runs in the browser and says sheets remain on the user’s device.
