Hey, on Chrome 32.0.1700.19 beta this:

Use the keyboard shortcut Command: Option + J (Mac)

doesnt work, as the shortcut seems to be Option + Alt + J.

Doh! Didn't know they changed it. Thanks for the heads up!

Did the menu access change? Or is it still View > Developer > JavaScript Console.

Nope, that one worked, and this is how I figured out the proper shortcut ;)

cmd + option + i always worked for me on mac. never tried J.
