choose file
file selection dialog
Puts up a standard Open File dialog, with title "Choose File" and default button "Choose." You can add a prompt; you can set the initial folder displayed. You can specify whether invisible files should be shown, whether packages should be treated as folders, and what types of file to display (can be a list of either four-letter file type codes or UTIs—see http://developer.apple.com/macosx/uniformtypeidentifiers.html—but not both). Returns an alias.
