So you spilled a drink on a keyboard. And how you should check what buttons are workin now? Do you need a new keyboard?
This is autotranslated version of this post.
Keyboard Checker website that will help to check all the keyboard keys for proper operation.
The only drawback of the site — it detects keystrokes only in English layout. It doesn't really matter. After all, the key will not work in any language.
When you hit physical button it is highlighted green on the virtual keyboard. In addition, the site will tell you how many buttons are left to click, and which was clicked last.
