Google Chrome now has the ability for users to complete command actions using the URL bar.
This means that you can type the command you are trying to complete into the URL bar instead of going into your Chrome Settings and navigating through different menus.
Example of some of the commands you can type are:
Clear cache/browsing data
Open Incognito Window
For directions on how to use Chrome Actions please check out these instructions.
While this can be a quicker way to access your settings, it is not mandatory and you can still complete these actions by going through your browsers settings.
