- // history database, so future versions will need the same values to match |

- // This is a subframe navigation. This is any content that is automatically |
- // loaded in a non-toplevel frame. For example, if a page consists of |

- // type. The user may not even realize the content in these pages is a |
- // separate frame, so may not care about the URL (see MANUAL below). |
- AUTO_SUBFRAME = 3, |
- |
- // For subframe navigations that are explicitly requested by the user and |
- // generate new navigation entries in the back/forward list. These are |

- // link was loaded. |

- // that did not look like a URL. For example, a match might have the URL |
- // of a Google search result page, but appear like "Search Google for ...". |

- // didn't type or see the destination URL. |

- // The user "reloaded" the page, either by hitting the reload button or by |
- // hitting enter in the address bar. NOTE: This is distinct from the |
- // concept of whether a particular load uses "reload semantics" (i.e. |
- // bypasses cached data). For this reason, lots of code needs to pass |
- // around the concept of whether a load should be treated as a "reload" |
- // separately from their tracking of this transition type, which is mainly |
- // used for proper scoring for consumers who care about how frequently a |
- // user typed/visited a particular URL. |

- // SessionRestore and undo tab close use this transition type too. |

- // The url was generated from a replaceable keyword other than the default |
- // search provider. If the user types a keyword (which also applies to |
- // tab-to-search) in the omnibox this qualifier is applied to the transition |
- // type of the generated url. TemplateURLModel then may generate an |
- // additional visit with a transition type of KEYWORD_GENERATED against the |
- // url 'http://' + keyword. For example, if you do a tab-to-search against |
- // wikipedia the generated url has a transition qualifer of KEYWORD, and |
- // TemplateURLModel generates a visit for 'wikipedia.org' with a transition |
- // type of KEYWORD_GENERATED. |
