previewing jumps

[jstaursky]

after pulling up with navigation window with Shift + F12, is it possible to keep my cursor there but preview jumps?
For example I see reference to somevar in fileA in the navigation window, my original window shows fileB. I want to be able to hit TAB on the reference in fileA to preview the jump using my original window (that currently shows fileB) before committing to the jump.
It gets annoying to jump to each reference and then have to reshift the focus back to the navigation window in order to see the next reference location.
