/* Toggles the grid on and off. Especially useful when drawing with just a pen without a mouse or keyboard, as toggling the grid by left-clicking with the pen is sometimes quite tedious.

See documentation for more details: https://zsviczian.github.io/obsidian-excalidraw-plugin/ExcalidrawScriptsEngine.html
