One thing I like of Linux is the command line.
Not just for automating tasks with fancy scripts or elaborate command pipelines. Also for basic stuff like quickly starting programs or accessing files.
With Chrome, I can do some of this on the web. For example, in the omnibox I type fragments of URLs or website names to visit the sites without clicking through bookmarks.
To go beyond this, Google added initial support for typing commands in the Chrome omnibox with address bar actions. The system is at an early stage. But you can make it more powerful, see below.
