Inverting the layermask

[Overread]

Lets say I add a layermask to a shot and use it to increase the sharpness of a selected area of that shot. If I then wanted to reduce (say) the noise of the opposite area is there a way to invet the layermask selection for another layer to do the noise editing on?

On the Layers Pallet, right click on the mask and select 'set layer mask to selection'. Then you can either invert that selection and make a new mask on your new layer...or you can hold down Ctrl (or is it Alt?) and click on the 'create layer mask' button (this will create a mask that is opposite of your selection).

ahh now the lack of CS3 hits me.
I am using elements 6 with an added layermask. I have tried your latter suggestion, and whilst I find I can copy the selection area, I can't paste it into a new layermask. I also note that when I do copy and paste the copied version is slightly transparant rather than beeing fully solid
Thanks though
