history.TransitionType

Values of this type are strings. Possible values are:

"link"

The user clicked a link in another page.

"typed"

The user typed the URL into the address bar. This is also used if the user started typing into the address bar, then selected a URL from the suggestions it offered. See also "generated".

The user clicked a bookmark or an item in the browser history.

"auto_subframe"

Any nested iframes that are automatically loaded by their parent.

"manual_subframe"

Any nested iframes that are loaded as an explicit user action. Loading such an iframe will generate an entry in the back/forward navigation list.

The user started typing in the address bar, then clicked on a suggested entry that didn't contain a URL.

"auto_toplevel"

The page was passed to the command line or is the start page.

"keyword"

The URL was generated using a keyword search configured by the user.
