New Bookmark Dialog
Use this dialog box to establish a new light-weight Mercurial branch (bookmark). The bookmark will immediately appear in the Branches pop-up. You can create both active and inactive bookmarks. By default, PhpStorm creates an active bookmark, so you are immediately switched to the new bookmark and it is marked with a tick in the Branches pop-up. If you do not want to want to move your development to the new bookmark right now, you can create an inactive bookmark and switch to it later. Note that tracking and updating is available only for the bookmark that is currently active. You can have only one active bookmark.
