For example -- if you type 2 + 2 you'll see exactly "2 + 2" until you press "=". The tool was made with touch-screen in mind and should be ready for touch-screen chromebooks. On devices with keyboard you can use the obvious keys: number keys, dot (floating point), +, -, *, /, Enter (=), ESC (C) and Backspace. The advanced ("scientific") functions are not yet accessible with keyboard shortcuts (but better keyboard support is planned for the next releases). The initial goal of this extension was to be a real-life example of jQuery Mobile (and it worked as such) but somehow, with the time, more options were added and it became full-featured scientific calculator. It is, however, still work in progress, so let me know if you find a bug, if something isn't workin…
