Mirror features (not parts)

Hi. When making an individual part, I want to mirror a feature, such as an extrude or a cut. It seems that I cannot do this, which is odd because this is an extremely important function.
How can I mirror a feature within an individual part?

Select "Feature mirror" from the pull-down menu in the mirror dialog.Senior Director, Technical Services, EMEAI6

When I try to mirror a feature, be it Extrude Remove, I cannot mirror it to the other part - there is no selection to mirroring scope (to which part/body it should be mirrored to).
but you can fake it by connecting your parts, then mirror, then cut them apart again
actually, better yet do this:
Use extrude NEW instead of extrude REMOVE
Then Boolean SUBTRACT that body
(Make sure you also select the other bodies you want this to be mirrored to)
Then Mirror both the EXTRUDE and the BOOLEAN features at the same time
It depends on the seed feature scope, if you select "merge with all" (or explicitly select the second part in the original feature), then the mirror feature will apply to a separate part as well.

Must have screwed up while testing.
First thing I did was try and re-create what Andres said, and I got his result, so I went down the wrong path
