But this doensn't crop off-workarea-parts of the layer. How can I crop them?

Rather than do a destructive delete, explore Layer Masks. They allow
you to 'bring back' bits you decide might be worth keeping after all,
and also allow you to fade the transition. A *far better* option,
because you don't need to chew back through your History to undo
accidental deletions.

I agree that a mask is better if you are not sure if you would ever want
to undo the crop. The suggestion that you cannot fade the transition if
you delete an inverted selection is wrong, however. Of course you can,
because you can feather the selection before you hit the delete key.

A very valid point, and of course you are right... I did not mean to
imply it's impossibility by that method, only to highlight the greater
ease with which such effects can be adjusted. For example, drawing a
polygon on the mask, and then using a number of the built-in, as well
as 3rd party, filters to affect the mask, thus providing much in the
way of creative effect.

However, by feathering a selection, you in effect apply the blur to
the entire selected area, whereas by using a mask, it can be done
sectionally. Even the humble 'Blur' family will allow a much more
diverse, and easier to work with, range of transitions.

Your point, however, is entirely well taken.

Everything you describe here can be done on a selection too. Just change
to 'Quick Mask' mode. A mask and a selection are technically the same
thing.
