By pressing various modifier keys (Control, Command, Option and Shift) while traversing FinderPop menus, you can modify FinderPop’s actions. The table below outlines the facilities available if there is no Finder selection while you’re traversing any FinderPop-related submenu. You should notice the mouse pointer changing as indicated.
  Command key — Show
Shows the chosen menu item (process or FinderPop item) in the Finder.
  Command-Option keys — Get Info
Get Info on chosen menu item (process or FinderPop item). If the chosen item is an alias to something, holding down the Shift key will Get Info or Show the alias, not the original item.
  Control-Command-Option-Shift — Trash or Kill
Kills process, or trashes chosen FinderPop menu item, or puts away a disk chosen from the Volumes submenu. (Ctrl-Cmd-Opt will kill a process; there’s no need to press Shift.)
If there is a Finder selection, you can change the behaviour of FinderPop when your mouse pointer moves over a menu item representing a folder while traversing a FinderPop related menu; sometimes the cursor changes automatically like the Finder’s.
  (No modifier) — Move
This is FinderPop’s default behaviour; it means that the Finder selection will be moved to the folder chosen from the FinderPop submenu. This is displayed only when the Finder selection and the chosen folder are on the same volume (disk.)
  Option — Copy
This will copy the Finder selection to the chosen folder. This cursor will automatically appear if the chosen folder’s volume and the Finder selection’s volume are different. Just like the Finder.
  Command-Option — Alias
This will create an alias of the Finder selection in the chosen folder. Again, just like the Finder.
All these modifier key chords are good piano practice, if nothing else…
