Chrome's omnibar shortcut, F6 vs Alt-D vs Ctrl-L?

Google Chrome's omnibar can be accessed using either:

• AltD

• CtrlL

• F6

• (list others in comments if you know of any)

What's the difference between these options?

Made a quick overview of the shortcuts! The difference is small but it does exist:

All keys do almost the same thing, they get the cursor's focus on the address bar but with the following differences in behaviour:

• Alt+D works in all situations focusing on the address bar.

• F6 Circles through the following:

  Address Bar, Bookmarks, New Tab Button, Current Window and Console (if open)
  

• Ctrl+E adds a question mark and if a domain is entered it gets searched in Google instead of directly accessing it. It is also intended for other type of entries - see this post.

• Ctrl+L works as the 'Clear Console' in the console, if open, or focuses the cursor on the address bar otherwise

Chances are that there is no difference at all and they just made so many shortcuts so that people who are familiar with other browsers would be able to guess right the first time.

I know another one :Ctrl+K ( or Ctrl+E )

It adds a "?" in the ominibox.

The "?" means your following input will be treat as keywords for search after pressing Enter.

Another key that adds a "?" in the omnibox is F3.
