Toolstrips have three main usage patterns that impact how they
are laid out, keyboard interaction and end-user behavior.
Joined in a ToolStripPanel
This means that the ToolStrip is typically repositionable within
the ToolStripPanel and across ToolStripPanels. The dock property is ignored, and
the size of the ToolStrip if not Stretch grows with more items. It usually does
not participate in Tab order.
Docked
The ToolStrip is docked to one side of a container, is in a fixed
position and size expanding over the entire edge to which it is docked. It usually
does not participate in Tab order.
Absolutely Positioned
This mode is using the ToolStrip just like a control. It is placed
via the location property, has a fixed size and typically participates in the Tab
order.
