Trim > delete trimmed parts

Hi,

When mutual trimming 2 surfaces A and B the trimmed part
is hidden within those surfaces.

To delete the trimmed part I cut A and B, then select and delete
the trimmed part,and insert A and B.

Is there a quicker way to delete the trimmed part like
a mutual trim function which automatically deletes the trimmed
part ?
