public enum TransitionType
  Member nameValueDescription
LinkClicked0 Source is a link click or the JavaScript function. This is also the default value for requests like sub-resource loads that are not navigations.
Explicit1 Source is some other "explicit" navigation action such as creating a new browser or using the LoadURL function. This is also the default value for navigations where the actual type is unknown.
AutoSubFrame3 Source is a subframe navigation. This is any content that is automatically loaded in a non-toplevel frame. For example, if a page consists of several frames containing ads, those ad URLs will have this transition type. The user may not even realize the content in these pages is a separate frame, so may not care about the URL.
ManualSubFrame4 Source is a subframe navigation explicitly requested by the user that will generate new navigation entries in the back/forward list. These are probably more important than frames that were automatically loaded in the background because the user probably cares about the fact that this link was loaded.
FormSubmit7 Source is a form submission by the user. NOTE: In some situations submitting a form does not result in this transition type. This can happen if the form uses a script to submit the contents.
Reload8 Source is a "reload" of the page via the Reload function or by re-visiting the same URL. NOTE: This is distinct from the concept of whether a particular load uses "reload semantics" (i.e. bypasses cached data).
