Hi,
I have two quetions about the Selection function/process
- When I Feather a selection and run a process in it, the edge of the selection is softer, as I would expect. If I use a brush in a feathered selection, no feathering occurs. How can I feather a selection and use a brush in the selection, so that the bordered is feathered?
- When I apply a process to a selected region on the canvas, it appears that the process runs on the entire canvas, but since there is a selection, everything but the selection is masked out on the canvas. For large canvas image, when I use a complex msg, for instance, this can be an extremely lengthy process. Is there a more efficient way of processing a selected area?

hmm. I misslabeled the question.
It should read "Feathering a selection, doesn't seem to feather any BRUSH that is applied."
Selection feathering is going top work the way you want it to for things like image operation effects, vectorizer effects, interactive warp or adjust effects, etc.
The paint synthesizer works with the selection in a different way. The reasons have to do with the history of how the program was developed, some aesthetic considerations, and the desire for speed when working with with interactive painting.
If you read the 'Paint Masking' section of this tip post on 'how to select and mask the canvas', it discusses the different high level masking options for masking your live painting with the current selection.
Note that if you are working with vector paint rather than raster paint effects, you most likely are not going to be able to do the hard nib masking option, just the path masking. This has to do with how vector painting works under the hood.
As a work around that involves some effort, you could duplicate your canvas in a different layer, do an unmasked painting there, then use the Fixed Image ip op effect with a feathered selection mask to mask a copy of the duplicate layer with the unmasked painting back into your original layer. because this is an ip op effect, the masked feathered selection will work like you want it to.
If you are working with raster paint effects, there is a way to configure the raster paint effect in the paint synthesizer so that the Blend Modulation is based on the Current Selection Region. This will modulate the paint blend to take into account whatever is in the current selection buffer, so if your selection is feathered then the paint application will blend accordingly.
