What is a keyboard tester?

A keyboard tester is a digital tool that helps you verify if every key on your physical keyboard is working correctly. When you press a key, the tester detects the input and provides visual feedback, allowing you to identify stuck, unresponsive, or malfunctioning keys. This is especially useful when buying a used keyboard, diagnosing typing issues, or testing gaming keyboards where every keypress matters.

What is the Estonian Keyboard Layout?

The Estonian keyboard layout is based on the ISO standard QWERTY layout with specific modifications for the Estonian language. It features dedicated keys for Estonian-specific letters that don't exist in standard English:

  • Õ (õ) - A unique letter found only in Estonian, Finnish, and a few other languages, positioned where the right bracket key is on US keyboards
  • Ä (ä) - Common in Estonian words, positioned where the apostrophe/quote key is on US keyboards
  • Ö (ö) - Used frequently in Estonian, positioned where the semicolon key is on US keyboards
  • Ü (ü) - Essential for Estonian spelling, positioned where the left bracket key is on US keyboards

The Estonian layout also uses the ISO physical layout standard common in Europe, featuring a tall L-shaped Enter key that spans two rows, an extra key to the right of the left Shift key, and specific symbol placements that differ from ANSI keyboards. This layout allows Estonian speakers to type all necessary characters efficiently without using complex key combinations.
