Menus and dialogue boxes

What is a menu?
A menu in the desktop is similar to a menu in a restaurant — it's a list of things to
choose from. In a foreign restaurant, if you can't actually speak the language, you can
point at the menu with your finger to tell the waiter which dish you want (assuming
that you know what the menu means!). On the computer, you move the mouse to point
at your choice from the menu. This is the main way of doing things in the RISC OS
desktop.
Menu options shown in grey (like Clear selection above) are not available at that time.
Often you must perform another action before the option becomes available.

Using menus

To display a menu, click the Menu (middle) mouse button over a window, or over an
icon on the icon bar, or over a blank area of the desktop (the latter will display the
Pinboard menu — see the section entitled Pinboard on page 53).
The menu displayed will depend on where the pointer is on the screen at the time,
whether you have previously selected an icon, and on the application you're using.
Cancelling an unwanted menu
If you press Menu by mistake, or decide you don't want a particular menu after all, you
can make a menu disappear by clicking Select on a blank area of the desktop or icon
bar.
