On a 1-, 2-, or 3-button mouse, the mouse buttons are assigned
to various functions, which are defined in tables later in this
appendix. Often a 2-button mouse can use chording as a way to simulate
a 3-button mouse, where MB1+MB2 (chorded) would be equal to MB3.
Motif supports two different mouse models: Separate selection and transfer operations,
where: MB1 is used only for selection and
activation MB2 is used only for data transfer and direct manipulation
Integrated select and transfer operations, where
MB1 is used both for selection and activation and for data transfer
and direct manipulation
The actual way that the mouse buttons are assigned depends
on the number of mouse buttons available, as well as whether or
not selection and transfer operations are integrated or separate.
Regardless of the way that the buttons are actually assigned, a
number of “virtual” mouse buttons are defined as follows: - SELECT
A virtual mouse button used for selection and activation.
SELECT is always MB1 (the leftmost mouse button for a right-handed
person). - ADJUST
A virtual mouse button used for adjusting a selection.
ADJUST is always Shift MB1. In
addition, on a 3-button mouse, with integrated selection and transfer,
ADJUST may optionally be assigned to MB2. - TRANSFER
A virtual mouse button that may be used for data
transfer and manipulation operations. With separate selection and
transfer, TRANSFER is always assigned to MB2. With integrated selection
and transfer, TRANSFER is MB1 (integrated with SELECT), and on a
3-button mouse may also optionally be assigned to MB2. - MENU
A virtual mouse button used to select pop-up menus: On a 3-button mouse, MENU is always
assigned to MB3. On a 2-button mouse with integrated selection and
transfer, MENU is assigned to MB2. If neither of the previous applies, MENU is assigned
to Alt MB1.
Table C-1 “Assignments for 2- or 3-Button
Mouse with Separated Selection and Transfer” lists
the virtual mouse buttons assigned to a 2- or 3-button mouse with
separated selection and transfer. Table C-1 Assignments for 2- or 3-Button
Mouse with Separated Selection and Transfer | Operation
Name | Binding |

| SELECT | MB1 | | ADJUST | Shift
MB1 | | TRANSFER | MB2 | | MENU | MB3 on a 3-button
mouse, or Alt MB1 on a 2-button
mouse. |
Table C-2 “Assignments for 1-,
2-, or 3-Button Mouse with Integrated Selection
and Transfer”
lists the virtual mouse buttons assigned to a 1-, 2-, or 3-button
mouse with integrated selection and transfer. Table C-2 Assignments for 1-,

MB1. This may also optionally be MB2 on a 3-button mouse. | | TRANSFER | MB1 (integrated

be one of the following: Alt MB1 on a
1-button mouse
|
| | | |  | NOTE: On a 3-button mouse with integrated selection and transfer,
if neither ADJUST nor TRANSFER are assigned to MB2, MB2 may be used
for application-defined purposes. | | | | |
