Caps Lock
Brazilian keyboards use the ABNT2 layout: Ç sits on the home row next to L, and accents are typed with dead keys for ´, `, ~ and ^ to get á, à, ã, â, é, ê, í, ó, õ, ô and ú.
Take the test, then follow the lessons from the home row. The hint shows when a dead key comes first. Type by position lets you practise even on another layout.
Your results show WPM, accuracy and the keys you miss most, and the adaptive mode turns them into exercises.
