What does "{Binding Path=.}" mean in WPF binding?

Question

What does {Binding Path=.} mean in a WPF binding?

I see some people use it, but couldn't find any explanation.

Are there any other special symbols in binding syntax (other than {Binding /})?

I found this WPF Binding CheatSheet a few months back and find it very useful, especially for anyone learning WPF. There are some spelling mistakes within it, but it is still quite good.

Here is a small excerpt (which is supposed to have tabular formatting):

Basic Binding   
{Binding}  Bind to current DataContext. 
{Binding Name}  Bind to the “Name” proeprty of the current DataContext. 
{Bindind Name.Length}  Bind to the Length property of the object in the Name property of the current DataContext. 
{Binding ElementName=SomeTextBox, Path=Text}  Bind to the “Text” property of the element XAML element with name=”SomeTextBox” or x:Name=”SomeTextBox”.
