Selection Options




What are the options when selecting?

  Replace (the default), add, subtract and intersect -- below is a labelled screenshot of the options box that pops up when you double-click on the selection items in the toolbox:





  As mentioned, the default is to replace any previous selection. So as soon as you start a new selection, the old one disappears. Fine for simple little things, but if you do something a bit complex (such as zoom in to lasso a piece of an area at a time, or use the fuzzy select to pick areas of similar color) then you would need to add.   The image above lists the shortcuts for these options, but I will list them below in case you can't see the image:

			replace   -->  default, no key shortcut needed
			add       -->  Shift
			subtract  -->  Ctrl
			intersect -->  Ctrl and Shift
			



Let's see these in action . . .

  Little demos should make these options clearer, so here you go. First up is an example using the fuzzy select (select contiguous region) grabbing the yellow pedals of a flower. By holding down the shift key, one pedal after another is selected.




  Here is a flash demo selecting an area with the fuzzy select tool, the default is to replace an area when another is selected.
