So, in the example you describe above, if all 5 tracks were next to each other...
expand layers on every track...
f5 to ensure smart tool
right click + drag to expand the lasso to select all layers on all 5 tracks.
f10 once or twice to get the mute tool (depending on what you used last).
now, click in the top half of one of the selected lanes
ctrl+shift+a to unselect all
f5 to get smart tool
next, ctrl click all the third lane of each of the five tracks
f10 to get mute tool and click in the top half of one of the selected tracks and it will turn off mute on all five disparately selected lanes.
pretty fast... I don't know. Solo would be how I would probably do it, but muting would work too and wouldn't be all that slow.
