+ToolManager
+-----------
+
+Federico Ariza wrote the new `matplotlib.backend_managers.ToolManager` that comes as replacement for `NavigationToolbar2`
+
+`ToolManager` offers a new way of looking at the user interactions with the figures.
+Before we had the `NavigationToolbar2` with its own tools like `zoom/pan/home/save/...` and also we had the shortcuts like
+`yscale/grid/quit/....`
+`Toolmanager` relocate all those actions as `Tools` (located in `matplotlib.backend_tools`), and defines a way to `access/trigger/reconfigure` them.
+
+The `Toolbars` are replaced for `ToolContainers` that are just GUI interfaces to `trigger` the tools. But don't worry the default backends include a `ToolContainer` called `toolbar`
+
+
+.. note::
+	For the moment the `ToolManager` is working only with `GTK3` and `Tk` backends.
+	Make sure you are using one of those.
+	Port for the rest of the backends is comming soon.
+
+	To activate the `ToolManager` include the following at the top of your file:
+
+	 >>> matplotlib.rcParams['toolbar'] = 'toolmanager'
+
+
+Interact with the ToolContainer
+```````````````````````````````
+
+The most important feature is the ability to easily reconfigure the ToolContainer (aka toolbar).
+For example, if we want to remove the "forward" button we would just do.
+
+ >>> fig.canvas.manager.toolmanager.remove_tool('forward')
+
+Now if you want to programmatically trigger the "home" button
+
+ >>> fig.canvas.manager.toolmanager.trigger_tool('home')
+
+
+New Tools
+`````````
+
+It is possible to add new tools to the ToolManager
+
+A very simple tool that prints "You're awesome" would be::
+
+    from matplotlib.backend_tools import ToolBase
+    class AwesomeTool(ToolBase):
+        def trigger(self, *args, **kwargs):
+            print("You're awesome")
+
+
+To add this tool to `ToolManager`
+
+ >>> fig.canvas.manager.toolmanager.add_tool('Awesome', AwesomeTool)
+
+If we want to add a shortcut ("d") for the tool
+
+ >>> fig.canvas.manager.toolmanager.update_keymap('Awesome', 'd')
+
+
+To add it to the toolbar inside the group 'foo'
+
+ >>> fig.canvas.manager.toolbar.add_tool('Awesome', 'foo')
+
+
+There is a second class of tools, "Toggleable Tools", this are almost the same as our basic tools, just that belong to a group, and are mutually exclusive inside that group.
+For tools derived from `ToolToggleBase` there are two basic methods `enable` and `disable` that are called automatically whenever it is toggled.
+
+
+A full example is located in :ref:`user_interfaces-toolmanager`
