- Ctrl-shift-C lets you inspect DOM elements with mouseover. This is the same as clicking the little magnifying glass in the tools.
- In Elements, the panels on the right show the live state of the DOM, CSS, etc. Most bits are editable as well as inspectable.
- In Scripts, you can set breakpoints by clicking on the line numbers.
- The docs describe a cool-sounding network page that I don’t have in my Chrome/stable. May be only available in developer for now?
- There’s ridiculously powerful performance tools built in. Learning it all would take hours, but quickly: go to Timeline, click the round record button, reload your page, then click record again to turn off recording. There’s a profiler too, for statistical profiles. Both seem to work better in Incognito mode so you don’t have any extensions.
- The console scripting prompt has some limited support for jQuery-like DOM identification of elements.
