Comment 2 for bug 699585

You can make a 'move selected to crosshair' using my distalign plugin (find it via gedasymbols.org)

I just made a mouse binding (in pcb-menu.res) like:

Right {
     # normal stuff here
     ctrl = { Align(X,Marks,Crosshair) Align(Y,Marks,Crosshair) }
}

Align() can do lots of other things, but if you choose the target coordinate to be the crosshair and do both axes, it is essentially 'warp to crosshair'
