Canvas: Selection inspector

This inspector contains representations of all the different styles of objects on the canvas.
Each style of object has a representation of the object and a pair of numbers. The first number is how many objects you have selected which match that style; the second number is how many objects of that style exist on the canvas.
Click a well to select all objects of its type. You can then use the Style inspectors and Properties inspectors to modify the objects on the canvas as if you'd clicked them individually. This is convenient if you'd like to, for example, change all blue diamonds to pink hearts.
You can also drop a style chit from the Style: Summary inspector onto a well in this inspector to apply the style to all associated objects.
The Sort using styles... pop-up menu contains style attributes that you can use to differentiate types of objects from one another. For instance, if you want objects with different fills to be considered different types, but you don't care about whether their strokes are different, select Fill and deselect Stroke.
