Graphical Input with a Mouse
The default button mapping listed in the Button Mappings dialog are appropriate for a two-button mouse, and allow you to simulate having a third mouse button:
- The Data button, which is used to enter data points, is mapped to the left-hand mouse button.
- The Reset button, which is used for resetting and for accessing the Reset pop-up menu and the view control pop-up menu, is mapped to the right-hand mouse button.
- The Tentative button, which is used to enter tentative snap points, is invoked by clicking the left-hand and right-hand mouse buttons at the same time. This is called a button "chord" and serves as a third button.
If you are using a three-button mouse, you may want to change Tentative to use a single button (rather than the two-button chord) for faster operation.
Using a Scrolling Mouse
If your mouse has a wheel, you can use the mouse wheel as the middle mouse button or as a wheel for scrolling to manipulate view windows and dialog scroll bars. You can also use it to zoom in and out of designs and enter tentative snap points.
You can either choose to accept the default settings for the mouse wheel or you can customize the button assignments.
You must have the required drivers for your mouse already installed on your system.
Default Mouse Button Assignments and Key Combinations
Other types of input are possible by combining mouse clicks and mouse wheel movement with key combinations. Here is the list of system default mouse button assignments:

Displaying Pop-up Menus to Left or Right
The pop-up menus such as tooltips and drop-downs on ribbon components, Work page, and others can be displayed on the left or the right of the cursor. This is particularly useful while using a Tablet PC and is controlled by the Handedness setting in the Tablet PC Settings dialog of Windows operating system. If it is set to "Right-handed", menus will pop up to the left so that the hand doesn't obscure the menu. If it is set to "Left-handed", menus will pop up to the right. By default, it is set to Left-handed. On the desktop computers or laptops, Bentley View always displays it as left-handed.
