If you do web development, you probably already know that you can get Chrome to emulate a variety of non-desktop devices.

If this is news to you, open up the Developer Tools (⌥ + ⌘ + I ) and then select the mobile icon in the top left corner (or ⌘ + ⇧ + M ). Ta-Daah!!!

Now, in the main browser window (you may have to click on it once to bring it back into ‘focus’), if you move your mouse over the content, you’ll see your mouse-cursor is now a translucent circle which emulates touch events.

But, while tweaking a mobile layout, I accidentally just bumped into the fact that if you hold down the Shift ⇧ key, your mouse will turn into a cross-arrow[^n] and then as you click it emulates some sort of two-finger spreading behavior.

How ‘bout that now?
