Understanding Keyboard Layouts
Keyboard layouts are the physical or virtual arrangement of keys on a typographic keyboard. Different countries and languages have developed their own standards to optimize typing speed and comfort for their specific linguistic patterns.
Why do mistakes happen?
The most common cause of "gibberish" text is forgetting to switch your operating system's input language. For example, if you intend to type "Hello" but your keyboard is set to Russian, you get "Рdkkj". KeySwap reverses this process mathematically, mapping each incorrect character back to its intended keystroke and then to the correct character in the target language.
Supported Standards
We support the most widely used standards including ANSI (US), ISO (Europe), and JIS (Japan). Our algorithms handle complex Shift-state logic, ensuring that even capitalized letters and special symbols found on the number row are converted accurately.
