Change Accessibility Keyboard preferences for accessibility on Mac
On your Mac, use the Keyboard pane of Accessibility Keyboard preferences to enable and set options for using the Accessibility Keyboard, an onscreen keyboard that lets you type and interact without using a physical keyboard.
To change these preferences, choose Apple menu > System Preferences, click Accessibility, click Keyboard, then click Accessibility Keyboard.
Enable Accessibility Keyboard
Display and use the Accessibility Keyboard.
Click to use the Panel Editor to create custom panels that are available from the Accessibility Keyboard.
Click to set General, Hot Corners, and Dwell options for the Accessibility Keyboard. See below for more information about the options.
General options for Accessibility Keyboard
Set general options for using the Accessibility Keyboard.
Use a light or dark appearance for the keyboard.
This setting is independent of whether you use a light or dark appearance on your Mac.
Fade panel after inactivity
After the specified period of inactivity, fade the keyboard by the specified percentage (at a lower percentage the keyboard is more visible, while at a higher percentage it’s less visible; at 100% it’s hidden). To make the keyboard fully visible again, move the pointer over the faded keyboard or, if it’s hidden, move the pointer.
This option is useful when you don’t need the keyboard for awhile, as when watching a movie, or when you want to see the part of the desktop that’s under the keyboard.
Play sounds for keys and dwell actions
Hear a sound when you select a key on the keyboard or when a dwell action is performed. (Selecting the Caps key makes a sound even when this option is not selected.)
Keys should be entered on
Input is entered or action taken on Mouse up or Mouse down.
Insert and remove spaces automatically
Let the Accessibility Keyboard manage spaces when you’re writing text. For example, it automatically corrects spacing after a period or between sentences, based on context.
Capitalize sentences automatically
Let the Accessibility Keyboard manage capitalization when you’re writing text. For example, it automatically capitalizes letters after a period (end of sentence), based on context.
Hot Corners options for Accessibility Keyboard
Set options for using Hot Corners with the Accessibility Keyboard.
Active Screen Corners
Set which action happens when you keep the pointer in a corner of the screen. Click the pop-up menu for a corner, then choose an action, such as Left Click.
Panel Follows Hide/Show Home Panel
When you use a hot corner to show or hide the Accessibility Keyboard or a custom panel, have the keyboard or panel move to the hot corner.
If you don’t want the keyboard or panel to move to the hot corner, deselect the checkbox.
Dwell options for Accessibility Keyboard
Set options that determine when to show Dwell action menus, which action to perform when you dwell on an item, how long to dwell on items, and more.
Allow dwell actions toolbar in panels
Make the toolbar available in the Accessibility Keyboard and custom panels.
Show dwell actions in menu bar
Show a status menu for dwell actions in the menu bar.
Always dwell in panels
Always use Dwell to select items in the Accessibility Keyboard and custom panels, even when Pause is selected in the menu bar or in the Options menu.
Left-click is the default action when dwelling in panels.
Set the color, such as green, of the dwell pointer when it’s shown.
Show the zoom window after the pointer is idle for the specified amount of time. The window magnifies the area you dwell on and the pointer.
The size of the zoom window is based on the size set for picture-in-picture zoom. To check that setting, choose Apple menu > System Preferences, click Accessibility, then click Zoom.
In the pane, click the Zoom style pop-up menu, choose “Picture-in-picture,” click Options, then adjust the size.
Note: Avoid changing other settings in the Zoom pane; they could interfere with the Dwell zoom window.
Hide dwell time indicators
Hide the dwell pointer and the countdown when dwelling.
Default dwell action
Choose the default action to perform when you dwell on an item—for example, right click, show the Scroll Menu, or drag and drop an item. Or choose to show the Options menu, which lets you switch between actions for one-time only use.
You can also choose an action from the dwell status menu, if it’s showing in the menu bar.
Auto revert to left click
After you select an action to perform, always make left click the next action performed.
This option is useful if you left-click items more often than you perform other actions.
Default dwell time
The amount of time to dwell on an item on the screen before an action is performed.
Panel dwell time
The amount of time to dwell on an item in a panel before a left-click action is performed.
Dwell movement tolerance
The distance, in pixels, you can move while dwelling on an item. If you move beyond this limit, the action isn’t performed.
To quickly enable or disable the Accessibility Keyboard using the Accessibility Shortcuts panel, press Option-Command-F5 (or if your Mac or Magic Keyboard has Touch ID, quickly press Touch ID three times).
To specify which options are available in the panel, choose Apple menu > System Preferences, click Accessibility, then click Shortcut.
