How do you use a bench vise to hold things in place?

I’d just like to apologize in advance for the inelegance of this particular visualization, but I hope it will help you make sense of what I’m trying to describe.  A bench vise is usually clamped to a table, or the edge of a workbench.  But if you leave it unclamped, it functions as a long lever, with a block of wood at the other end, and a screw on the other end.  So you can twist the block or screw into place
