QWERTY Keyboard Tester

What is this QWERTY keyboard tester?

This page gives you a family-level view of supported QWERTY layouts and quick links into each layout-specific tester.

When you open a layout page you can press letters, numbers, modifiers, arrows, and numpad keys, and the matching keys on the virtual keyboard will highlight so you can confirm your hardware and layout settings before gaming, typing, or remote support sessions.

Which QWERTY layouts and variants are included?

This family view groups multiple QWERTY layouts, such as US (00000409), United Kingdom (00000809), Finnish (0000040b), and more.

You can switch between layouts from the toolbar and then open dedicated variant pages for deeper testing, so you always test against a visual keyboard that matches your operating system and regional layout.

How do the highlight modes work for QWERTY keyboards?

Each layout tester includes three highlight modes so you can inspect your keyboard in different ways:

• Live highlight - keys glow only while they are held and fade shortly after release for real-time checking.
• Stay lit - keys stay highlighted after each press until you reset highlights, so you can see everything that fired during combos or macros.
• Find missing - every key starts in a primed glow, and when it registers a press it returns to normal, making missing or dead keys easy to spot at the end.

How does the Hide numpad toggle help with different QWERTY boards?

Each layout tester lets you adjust the numpad view to match your hardware. Not every QWERTY keyboard has a numpad, so this tester lets you show or hide the numpad column:

• Click Hide numpad to collapse the numpad when you are testing tenkeyless or laptop keyboards.
• Click Show numpad to bring it back when you want to verify Num Lock, operators, and navigation keys on full-size boards.

The toggle only changes the visual layout; your key presses are still detected either way.

How do I switch between QWERTY variants?

The toolbar above the keyboard gives you two levels of control:

• Layout - pick the QWERTY family from the dropdown when you want to focus on these layouts.
• Variant - open a specific layout page, such as US (00000409), United Kingdom (00000809), Finnish (0000040b), to test against that exact mapping.

Use this family page to browse layouts in the QWERTY family and then jump into their dedicated layout pages when you want detailed key-by-key checks that match your regional or OS mapping.

Which keys and shortcuts are supported across QWERTY layouts?

The QWERTY family tester is designed to cover all common keys for supported layouts, including:

• Letters, numbers, symbols, and punctuation in their layout-specific positions.
• Function keys (F-row), modifiers (Shift, Ctrl, Alt, AltGr, OS/Command), and arrow keys.
• Numpad digits, operators, and Enter on keyboards that include a numeric pad.

Most common shortcuts and game keybinds appear as separate key presses, but a few system-reserved shortcuts may still be blocked by your operating system or browser.

Where are QWERTY layouts commonly used?

QWERTY layouts are widely used on English and many European keyboards, including US, UK, Nordic, and Latin American boards in offices, gaming setups, and shared labs.

Using this tester family first helps you decide which exact variant matches your hardware, so you can then move into the matching variant page for detailed key-by-key testing.

Why do some keys not light up with certain QWERTY layouts?

If some keys do not highlight, it is usually because of technical limits rather than the tester itself:

• Your browser or operating system may intercept security-critical shortcuts before they reach the page.
• The keyboard may expose special macro, media, or Fn-layer keys that do not send standard key codes.
• Older or low-end keyboards can drop keys when many are held at the same time because of rollover and ghosting limits.

You can try the same keyboard on another device and press the keys one by one to confirm whether it is a hardware or software limitation.

Is this QWERTY keyboard tester safe and private to use?

Yes. All key detection happens locally in your browser, and keystrokes are used only to update the visual keyboard, counters, and highlight modes.

We do not store or log individual key press sequences in our own database. Our hosting and advertising providers may still process standard web request data (such as IP address, browser information, and page views) for security, analytics, and ads, as explained on our Privacy & Cookies page. As a best practice, avoid typing sensitive passwords while testing.

How does this QWERTY keyboard tester work internally?

This QWERTY keyboard tester runs entirely in your browser using JavaScript.

The tester listens for keydown and keyup events, matches the key code and value to the relevant layout profile, and highlights the corresponding key on the virtual board. The counters show your last key, total detections, and keys currently held so you can see rollover behavior and how many keys register at once.
