When troubleshooting keyboard issues, you might need to find out if the computer recognizes the keys being pressed on the keyboard.
A script for testing keypress events is called JAVASCRIPT KEY EVENT TEST SCRIPT.
A Windows program called WINDOWS ON-SCREEN KEYBOARD displays an on-screen keyboard for testing modifier keys and other unique keys.
A Windows application called PASSKMARK KEYBOARDTEST examines the keys that are pressed on keyboards with various layouts.
Let’s see how to test my alt key together.
Now that you’ve made sure every other key functions properly, check to see if Alt and Tab are registering. To check if the Alt and Tab keys are operating properly, go to the keyboard tester website and press each key separately.
Try using a different Alt key if one of the malfunctioning ones isn’t functioning. Proceed with the remaining fixes if the other Alt key proves to be ineffective.
If the keyboard driver is out of date, it’s possible that even when keys are registering correctly, the input may not be sufficiently fed into the system. The majority of the time, keyboard shortcuts that are not supported are largely caused by driver problems; Alt-Tab could be one of them. As a result, you must completely uninstall the keyboard driver from the computer.
In order to rule out this possibility, restart Windows Explorer.
Sometimes, when the Peek option is disabled in Windows settings, Alt-Tab does not register. When viewing any other window, you can use the peek option to navigate to your desktop by moving your mouse over the small rectangle in the lower-left corner.
Do you find that it’s easier to preview and switch between open windows when you use the Alt-Tab terminator? If so, you ought to remove the program. It makes switching between windows faster, but it can also make the built-in Alt-Tab function less effectively.
Your last option should be to modify the Registry if everything else fails. Many issues can be resolved by altering or creating new registry file settings, but if you don’t know what you’re doing, you could end up in danger. Therefore, skip this step if you are unfamiliar with adjusting registry settings.
How I test each key on my keyboard is the next topic.
If you’re in the market for a used laptop as well, here are four ways to make sure every key works.
-
To test a laptop keyboard, open a word processor (like Microsoft Word, Google Docs, or another one) and start typing each key on the keyboard one at a time.
-
Using an online keyboard tester is the second option, which allows you to test each key on your keyboard.
This method lets you test your entire keyboard, unlike the previous one. Proceed to any keyboard tester, like keyboardtester, and begin pressing each key individually.
-
You can use a virtual keyboard tool from a third party to accurately test the key combinations.
Third-party apps allow us to quickly verify whether key combinations are registering, which is an advantage this method has over the other two.
-
Device Manager is another place to check for hardware updates. Examining them could assist you in determining whether there is a keyboard issue.
