While physical keyboards are the primary way to interact with a Mac, they are not accessible to everyone. Some users experience motor control issues, while others might temporarily lose the use of their physical keyboard due to a hardware failure or a spilled cup of coffee.
To ensure macOS remains fully navigable without physical keystrokes, Apple includes a highly customizable, on-screen typing tool called the Accessibility Keyboard. This is not just a simple visual representation of keys; it is a powerful assistive technology that includes word prediction, custom macros, and Dwell controls (typing without clicking).
How to Enable the Accessibility Keyboard
The Accessibility Keyboard is hidden deep within the System Settings, as it completely alters how input is handled by the operating system.
- Click the Apple menu () in the top-left corner of your screen and select System Settings (or System Preferences on older macOS versions).
- In the left-hand sidebar, scroll down and click on Accessibility.
- In the main window, scroll down to the “Motor” section and click on Keyboard.
- Look for the section labeled “Accessibility Keyboard” and toggle the switch to turn it On.
A large, fully functional keyboard will immediately appear floating on your screen. This window stays permanently on top of all other applications, ensuring it is always available when you need to type.
Basic Features of the On-Screen Keyboard
You can use your mouse or trackpad to click the keys on the screen. The keyboard behaves exactly like a physical one, but it includes several intelligent features to speed up your workflow.
- Word Prediction: As you begin clicking letters, a row above the keys will suggest complete words (similar to an iPhone keyboard). Clicking a suggested word instantly inserts it, saving you several clicks.
- Auto-Capitalization: The keyboard automatically capitalizes the first letter of a new sentence.
- Sticky Keys: If you click the Shift or Command key, it will “stick” in the pressed position, allowing you to easily execute complex shortcuts (like Command + Shift + 4) without needing to hold down multiple buttons simultaneously.
If the keyboard is taking up too much screen real estate, you can click and drag the corners of the window to resize it, or click the minimize button in the corner to collapse it into a tiny toolbar.
How to Use Dwell Controls (Typing Without Clicking)
For users who can move a mouse cursor but have difficulty physically clicking the mouse button, the Accessibility Keyboard offers “Dwell” support. This allows you to type simply by resting your cursor over a key for a specific amount of time.
- In the same Accessibility > Keyboard settings menu where you enabled the feature, click the small Information (i) button next to the toggle switch.
- Click on the Dwell tab.
- Turn on the toggle for Allow Dwell actions in panels.
You can adjust the “Dwell time” slider to determine how long you must hover over a key before it registers. For example, if you set it to 1.5 seconds, simply moving your cursor over the letter ‘A’ and holding it perfectly still for 1.5 seconds will automatically “press” the key.
Creating Custom Keyboards (Panels)
The standard QWERTY layout is not always the most efficient. Through the Panel Editor, you can design your own custom keyboards.
In the Accessibility Keyboard settings menu, click the Panel Editor… button. This opens a separate application where you can design a custom layout from scratch. For example, if you spend all day editing video, you could create a tiny, custom panel that only contains four massive buttons specifically programmed to trigger your most-used video editing macros, entirely replacing the need for the full alphabet.
