Press the ALT key to display all ALT key shortcut options. Shortcuts are represented by underlined letters in the menu bar, as seen in the highlighted areas in the example:
After pressing ALT, use shortcuts by pressing the appropriate keys. For example, pressing ALT- F + O + R opens the Document Retrieval dialog box.
When your cursor is positioned on the drop-down menu, use arrow keys to move vertically and horizontally through menu options. When your cursor is positioned on a vertical drop-down menu, choose a shortcut within that menu by typing the underlined character. For example, select ALT- F to enter the File menu, press O to display the File | Open menu.
