Keyboard shortcuts not working but typing works

You can type letters, but shortcuts such as copy, paste, save, or undo do nothing. That does not always mean a key is broken. A shortcut can be intercepted by the app, the operating system, a keyboard setting, or another program.

Test whether the keys register together, then check where the shortcut is being handled. The Keyboard Test can help separate a keyboard input problem from a shortcut or software problem.

Test the keys in the shortcut

1. Open the Keyboard Test. Press each key in the shortcut on its own, including the modifier key such as Ctrl, Alt, or Shift.
2. Press a simple combination that the browser will not use itself, such as Ctrl + J. Check whether both keys register while held together.
3. Try the combination again in the app where the shortcut fails. Confirm that the app has focus and that you are using the shortcut listed in its menus or help.
4. If possible, try the same shortcut in another app that supports it. For example, test copy and paste in a text editor as well as in the original app.

Some key combinations control the browser or operating system, so a web page cannot test them reliably. Do not use a shortcut that might close a tab or change something important during the test.

What the result means

One key does not register on its own

The issue may be a faulty key, a connection problem, or a keyboard driver problem. Try the key in another app and, if you can, connect another keyboard. If the same physical key fails everywhere, follow the hardware checks below.

Each key works alone, but they do not register together

This points to a rollover limit or a problem with the keyboard's handling of simultaneous presses. Rollover is the number of keys a keyboard can report at once. The Keyboard Test checks how many keys work together, but the result can vary with the combination and the keyboard's design.

The keys register together, but the shortcut fails in one app

The keyboard is probably sending the input. Check whether the app uses a different shortcut, whether a text field or dialog has focus, and whether another command has been assigned to the same combination.

The shortcut fails across several apps

A system setting, remapping utility, accessibility feature, or background program may be changing the input. Try the fixes below before replacing the keyboard.

How to fix it

1. Check the app's shortcut and focus. Look in the app's menus for the command and its current shortcut. Click the document or control you want to use first. A shortcut may not work while a search box, dialog, or another window has focus.
2. Press the modifier key again. Tap Ctrl, Alt, Shift, or the ⌘ Command key a few times. If a modifier seems stuck, disconnect and reconnect the keyboard, then test it again.
3. Turn off accessibility key features temporarily. On Windows 11, open Settings › Accessibility › Keyboard and check Sticky Keys and Filter Keys. On macOS, open System Settings › Accessibility › Keyboard and check Sticky Keys and Slow Keys. These features change how key presses and combinations are handled.
4. Check for remapping or keyboard software. Close keyboard utilities, macro tools, game profiles, and remapping apps temporarily. If the shortcut starts working, review that program's profile for a reassigned modifier or command.
5. Check the keyboard layout. A different layout can put symbols and punctuation in different places, which can make a symbol-based shortcut seem wrong. On Windows 11, check Settings › Time & language › Language & region. On macOS, open System Settings › Keyboard and review the input source under Text Input.
6. Reconnect or restart. Unplug a wired keyboard and try another USB port. For a wireless keyboard, check its battery and reconnect it. Restart the computer if the issue continues across several apps.

When it may be the keyboard

Test the same keys on another computer, or try a different keyboard on yours. If one key or combination consistently fails on another device too, while other keys work, the keyboard may have a damaged switch, cable, or internal controller. For a wireless model, replace the batteries and test the receiver or Bluetooth connection before deciding it is faulty.

If only a particular multi-key combination fails, that does not by itself prove the keyboard is broken. Some keyboards cannot report every key combination at once. Check the manufacturer's specifications or use a different shortcut if the app allows it. If individual keys also fail on another device, consider warranty service or a replacement.

Why some shortcuts cannot be tested in a browser

A browser page only receives the key events that the browser and operating system pass to it. The Fn key never reaches the browser. The Windows key, Print Screen, and laptop shortcut keys for functions such as brightness, volume, and Wi-Fi are usually handled by the operating system first. A browser test cannot confirm that those system actions work.

For a fair comparison, test ordinary keys and a combination the browser does not reserve, then try the failing shortcut in the app that is supposed to handle it. That helps show whether the issue is with key input or with the shortcut itself.
