Shortcut: <F1>
You can use the <F1> key in an active window, in a dialog box, or above a menu command in order to open the 'Help' 'Contents and search'. When you perform a command from the menu, the help for the command called up at that time is displayed. You can also highlight a text (for example, a key word or a standard function) and press <F1> to have the help displayed for that item.
