This mode can be entered via the simple mode Add way action, via a long click otherwise, and via the Append action in way and node selection modes.
You can then do one of three things
The complete way can be moved without leaving this mode.
Tapping the icon once will undo the last addition of a node.
When the snap function is active, newly created nodes near to other nodes and ways will snap on to these automatically creating connections. It the checkbox is not checked nodes will be created without merging with other objects. You can toggle this while you are drawing a way.
Note: when the checkbox is not checked you need to manually close closed ways, for example a building outline.
Create the current new object, launch the property editor and immediately display the preset tab. In multi-pane mode this will simply start the property editor.
If two consecutive nodes overlap with nodes of an existing way you can follow the existing way to one of its nodes after clicking the button.
Adds address tags with prediction. If the way is closed this will add the predicted address tags and start the property editor. If the way is not closed an address interpolation is created and a dedicated editor is started.
