Miscellaneous RotoShape Viewer Controls

Button	Name	Action
	Toggle Fill/No Fill Mode	Quickly toggles the rendering of the shape on and off.
	Show/Hide Tangents	Controls the tangent visibility. When in Pick mode, only the active knot displays a tangent; None hides all tangents; All displays all tangents.
	Lock/Unlock Tangents	Locks or unlocks the tangents of adjacent knots when moving any knot.
	Enable/Disable Transform	A really annoying control to pan the entire collection of shapes; it is off by default.
	Key Single/Multiple Shapes	Indicates whether you are keyframing the active shape or all shapes when you roto.
	Toggle Path	If the main onscreen transform tool is turned on, this toggles the visibility of the animation path; it doesn't have a purpose if the tool is turned off.
	Enable/Disable Shape Transform Control	Turns the shape transform control on and off.
	Import/Export Shapes	Imports and exports shapes.

The Import Shapes button can be used to import shapes from programs such as SilhouetteFX's Roto, available at www.silhouettefx.com.
