The mouse buttons
The mouse buttons
The mouse has three buttons, known as Select, Menu and Adjust:
The Select button is used most of the time to select icons displayed on the screen, or to
choose from menus.
The Menu button makes a menu appear. Menus are described in Menus on page 23.
The Adjust button does a variety of things, mostly useful variants of what the Select
button does. Keeping a menu on the screen on page 25 includes one instance, and the
RISC OS 3 User and Applications Guide describes many more.
Mouse techniques
The following mouse techniques are all you need to start using your computer:
clicking – pressing the mouse button just once and then releasing it immediately.
double-clicking – pressing and releasing twice in quick succession. This is used to
initiate an action, or to load an application, for example.
dragging – moving an object from one place to another whilst holding down the
Select (or Adjust) button.
Clicking and dragging techniques are summarised on the following pages.
