NavigUp

Navigate to parent address. It means removing page anchor (#xxx), query string (?xxx), file or the last directory (/xxx), port number (:xxx), sub-domain (xxx.) or secure layer (https -> http), whichever is first found (preserving mentioned order).

You can use the mouse and click NavigUp's icon (present on the right side of the address bar) or go with the keyboard and press one of the supported shortcuts.

== Shortcuts == Use (Ctrl+)(Shift+)Alt+Up for it. Shift means going up one more level, Ctrl - additional two levels. Ctrl and Shift can be combined. If you click extension's icon (in the address bar) many times within one third of second, then you'll go up many levels at once.

== Permissions ==

1. "Access your data on all websites." (content script executed when URL matches "http:///", "https:///", "ftp:///") Content script is used only for catching keyboard shortcuts (commands API doesn't support Ctrl+Alt combinations) and setting up a popup (if it is turned on).
2. "Access your tabs and browsing activity." ("tabs" permission) "tabs" permission is a broad one, but it is used only for accessing or modifying particular tab's URL within background page.
