Because not all keyboards are the same, it is difficult to specify keys that are correct for every manufacturer's keyboard. To solve this problem, this guide describes keys using a virtual key mechanism. The term virtual implies that the keys as described do not necessarily correspond to a fixed set of actual keys. Instead, virtual keys are linked to actual keys by means of virtual bindings. A given virtual key may be bound to different physical keys for different keyboards.
See Chapter 13 of this book for information on the mechanism for binding virtual keys to actual keys. For details see the VirtualBindings(3) reference page in the Motif Programmer's Reference.
This guide assumes a 3-button mouse. On a 3-button mouse, the leftmost mouse button is usually defined as Btn1, the middle mouse button is usually defined as Btn2, and the rightmost mouse button is usually defined as Btn3. For details about how mouse buttons are usually defined, see the VirtualBindings(3) reference page in the Motif Programmer's Reference.
