Full Keyboard Access on Mac: what it does and when to turn it on
macOS has a mode that lets you reach every button, checkbox, menu, and window on screen without ever touching the trackpad. It's called Full Keyboard Access, it's free and built in, and most people never turn it on — partly because it's buried in Accessibility, and partly because it's easy to confuse with a lighter setting that does something similar. This guide covers what Full Keyboard Access on a Mac actually does, the commands worth learning, and — importantly — when the simpler option is the one you really want instead.
What Full Keyboard Access actually does
Turn it on and macOS starts drawing a highlight — a focus ring — around one element at a time. Tab moves that focus to the next control; Shift-Tab moves it back. Arrow keys move within a group (a row of radio buttons, a toolbar), and the Space bar activates whatever's focused, the same as a click.
The difference from ordinary tabbing is reach. With Full Keyboard Access on, the focus ring doesn't stop at text fields and the odd button — it can travel to the menu bar, the Dock, a window's toolbar, Control Center, a sheet that just slid down, the sidebar, and back into the content. Every region of the interface becomes keyboard-reachable, which is exactly what it was built for: it's an accessibility feature for people who can't use a pointer at all.
How to turn on Full Keyboard Access
The toggle lives in Accessibility, not the main Keyboard settings:
- Open System Settings → Accessibility (Apple menu → System Settings).
- Under the Motor section, click Keyboard.
- Turn on Full Keyboard Access.
Next to the toggle is an ⓘ button. Open it and you can customize how the focus ring looks (its visibility, color, and size — worth turning up if you keep losing track of it) and review or change the individual commands.
The commands worth knowing
Once it's on, the mode has its own vocabulary. Most of it is Tab-based, plus a few jumps to specific regions:
| Command | What it does |
|---|---|
| Tab / Shift-Tab | Move focus to the next / previous control |
| Arrow keys | Move within a group (radio buttons, a toolbar) |
| Space bar | Activate the focused control (click a button, tick a box) |
| Tab-H | Open Commands Help — the full, searchable list |
| Fn-Control-F2 | Jump to the menu bar (then arrow around or type to find an item) |
| Fn-A | Jump to the Dock |
| Fn-C | Open Control Center |
| Fn-N | Open Notification Center |
| Tab-W | Open the Window Chooser |
| Tab-A | Open the Application Chooser |
| Tab-F | Search the current window's controls |
| Tab-C | Move the pointer to the focused item |
If you only remember one, make it Tab-H — it opens the complete list on demand, so you never have to keep the rest in your head.
Full Keyboard Access vs Keyboard navigation
Here's the part that trips people up. macOS has two keyboard-focus settings, and for most people the lighter one is the better fit.
The lighter one is called Keyboard navigation. It lives in System Settings → Keyboard as a simple toggle (not in Accessibility). All it does is let Tab move focus between controls inside dialogs and web forms — so you can Tab to the "Don't Save" button and hit Space instead of reaching for the mouse. It's quiet, it doesn't paint a bold focus ring over everything, and it's the setting most people mean when they say they want to "Tab between buttons."
Full Keyboard Access is the heavier, whole-system mode. It's far more capable, but it also changes how Tab behaves everywhere and puts a prominent highlight on screen at all times — which can feel loud if you only wanted to skip the mouse in the occasional Save dialog.
| Keyboard navigation | Full Keyboard Access | |
|---|---|---|
| Where | System Settings → Keyboard | Accessibility → Keyboard |
| Scope | Buttons/controls in dialogs & forms | The entire interface |
| Reaches menu bar, Dock, toolbars | No | Yes |
| Visual focus ring | Subtle | Prominent (customizable) |
| Best for | Most people, occasional mouse-free moments | Full mouse-free control / accessibility need |
If you tried Full Keyboard Access, found it overwhelming, and turned it back off — try Keyboard navigation instead. It's probably the switch you actually wanted.
When to turn Full Keyboard Access on
Turn it on if you genuinely need to run the whole Mac without a pointer, or if you want to learn to reach every corner of the UI from the keyboard and don't mind the always-on focus ring. It's the most complete keyboard-control mode Apple ships, and it costs nothing.
Leave it off — and use Keyboard navigation — if your goal is just to stop grabbing the mouse for dialog buttons and forms. You get the 90% that matters without the visual noise.
The two jobs it still handles awkwardly
Full Keyboard Access is built to reach controls inside apps. The two things power users touch most — getting to the right window and placing or sizing a window — sit slightly outside its wheelhouse. Tab-W opens a window chooser, but there's no fast most-recently-used order, and window placement still means the native tiling chords (Globe-Control-arrows), which stop at halves and quarters with no thirds.
That's the gap two small, keyboard-first tools fill — and they work whether or not Full Keyboard Access is on:
- Let's Switch — hold Option-Tab to flip through your most recently used windows (not just apps), with a live preview of each, newest first; Option-` cycles one app's windows. Both are free. It's the "reach the exact window" job, done in one chord.
- Let's Tile — press ⌘↵ to summon a visible grid, then snap the window into it — nothing to memorize, because you can see the target. Free thirds (which macOS never offers natively), no subscription, no account.
Neither replaces Full Keyboard Access; they just do the two high-frequency window jobs that a general accessibility mode was never designed to make fast. For the bigger picture, see our guide to a mouseless Mac workflow.
Frequently asked questions
Where is Full Keyboard Access on my Mac?
System Settings → Accessibility → Keyboard (under the Motor section) → Full Keyboard Access. It is not in the main Keyboard settings — that pane holds the separate, lighter Keyboard navigation toggle.
What's the difference between Full Keyboard Access and Keyboard navigation?
Keyboard navigation just lets Tab move between controls in dialogs and forms. Full Keyboard Access is a whole-system mode that also reaches the menu bar, Dock, toolbars, and Control Center, with a prominent on-screen focus ring. Most people want the lighter Keyboard navigation.
How do I see all the Full Keyboard Access commands?
With Full Keyboard Access on, press Tab-H to open Commands Help — a searchable list of every command, so you don't have to memorize them.
How do I turn Full Keyboard Access off?
Go back to System Settings → Accessibility → Keyboard and switch Full Keyboard Access off. If you liked being able to Tab to dialog buttons, turn on Keyboard navigation (System Settings → Keyboard) so you keep that without the full mode.
Can I change how the focus ring looks?
Yes. Click the ⓘ button beside the Full Keyboard Access toggle to adjust the highlight's visibility, color, and size — useful if the default is too subtle or too loud for you.
Full Keyboard Access is one of the most powerful things hiding in macOS, but it's built for a specific need — total pointer-free control. If you just want a keyboard-first day without the overhead, pair the lighter Keyboard navigation toggle with a couple of purpose-built tools, and you get most of the benefit with none of the friction.
