Portuguese Keyboard Tester (Portugal)

The Portuguese layout on the picture

Keyboards sold in Portugal are ISO boards (tall Enter, extra key next to left Shift) with the Windows Portuguese layout. The letters are where a US keyboard has them; Ç takes the key right of L, and º ª the key after it. The number row keeps the digits but moves the symbols: “ on Shift+2, / on Shift+7, = on Shift+0, ’ and ? right of 0, « and » next to Backspace. The key left of 1 types \ and |.

Accents are dead keys. + and * take the key right of P, ´ and ` the key after it, and ~ and ^ the key next to Enter; ¨ is AltGr on the + key. The table under this text marks them “dead”: the key itself types nothing until you press a letter.

Switching to Portuguese

• Windows: Settings, Time & language, Language & region, Add a language, Português (Portugal). Switch with Win+Space.
• macOS: System Settings, Keyboard, Text Input, Edit, +, Portuguese. Mac keyboards for Portugal have their own legends, so symbols can differ from this picture.
• Linux (GNOME): Settings, Keyboard, Input Sources, +, Portuguese.

Testing it

Press every key once. Dead keys are the ones people think are broken: they light up here like any other key, even though nothing appears on screen until the next letter. If a key types the wrong character, check the layout the computer uses (in Chrome and Edge the line under the picture says whether it’s Portuguese). A key that never lights up is a fault; a key that lights up twice for one press is chatter, and the detector below the keyboard lists it with the gap in milliseconds.

The Portuguese keys at a glance

These keys differ from a US keyboard. The browser code is the name the key sends in the event log, taken from the US key in the same place. AltGr is the right Alt key; on Windows, Ctrl+Alt does the same. Keys marked "dead" type nothing on their own: press one, then a letter, for an accented letter (or Space for the mark itself).
