To toggle backwards searching, you need to press Alt + B in the search dialog.

Hab gerade kein OSX Rechner zur Hand um es selber zu testen (vor allem, welcher Modifier notwendig ist), aber vielleicht hilft es Dir ja:

Ctrl + W is the shortcut for searching. The same effect can be achieved by pressing the F6 key. After entering the search term, press Enter. To repeat the search, issue Alt + W. In this menu, you can select earlier searches using the arrow up/ down keys.

To toggle backwards searching, you need to press Alt + B in the search dialog.


For more shortcuts, press F1
