Selecting and inspecting DOM elements: you've done it many times before. Whether you right click the element and select Inspect (which isn't always all that accurate) or you use the DevTools' inspect tool with highlight-assist, it takes a couple clicks to get there.
There is a faster way.
Hit Cmd-Shift-C.
Chrome DevTools will be expanded open if it isn't already and your mouse pointer will be put in inspect mode with the highlight-assist. Find your DOM element, give it a click, and start inspecting!
