The underscores marked on the menu are there to indicate which key is the "access key" or "shortcut" to that option.

For example, the option Shipping Manager has the shortcut "S"

How you can use shortcuts on menu items will differ depending on which browser you are using.

Below is a list of shortcut keys found in common browsers:

• Google Chrome: Alt + <shortcut> - so to access the Shipping Manager, press Alt+S

• Mozilla Firefox: Shift + Alt + <shortcut> - so to access the Shipping Manager, press Shift+Alt+S
• Mac OSX (all Browsers): Ctrl + Alt + <shortcut> - so to access the Shipping Manager, press Ctrl+Alt+S
