Assistive mouse features provide alternative ways for users with motor impairments and limited mobility to use a mouse. Some of this functionality is provided by the Mousetweaks tool, which you can also invoke by using the command line. To obtain up-to-date command-line usage for the tool, run the man mousetweaks command.
To customize mouse features from the top bar of the GNOME desktop:
Starting from the System menu, select Preferences, and then select Assistive Technologies to open the Assistive Technologies Preferences tool.
Click Mouse Accessibility to open the Mouse Preferences tool.
Using the accessibility tabbed section of the Mouse Preferences, set the following mouse preferences:
Simulated Secondary Click: This function triggers a secondary click by holding down the primary button. Activating this feature enables you to perform secondary clicks by using the primary mouse button, which is useful in situations where you only have one mouse button. Select the Trigger secondary click by holding down the primary button check box to enable this setting. You can specify a length of time for a delay (ranging from Short to Long) by adjusting the Delay slider.
Dwell Click: This function provides the option to initiate a mouse click when stopping pointer movement. Select the Initiate click when stopping pointer movement check box to enable the feature. To specify a length of time for a delay (ranging from Short to Long), adjust the Delay slider. To specify a motion threshold (ranging from Small to Large), adjust the Motion threshold slider.
You can also choose from the following options for Dwell Click: Initiate click when stopping pointer movement and Choose type of click with mouse gestures.
Selecting the Initiate click when stopping pointer movement option enables you to also select the Show click type window option.
