New Bookmark dialog
Use this dialog to establish a new light-weight Mercurial branch (bookmark). The bookmark will immediately appear in the Branches popup. You can create both active and inactive bookmarks. By default, RubyMine creates an active bookmark, so you are immediately switched to the new bookmark, and it is marked with a tick in the Branches popup. If you do not 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. For details, see Bookmarks and Manage Mercurial branches and bookmarks.
In this field, type the name of the bookmark. This identifier will always point at the head of the new light-weight branch as you commit changes. You can use this name to identify the head of the relevant light-weight branch when during update or merge.
