Use these shortcuts to make practice more convenient on PC and Mac.
If you use Apple's Magic Keyboard or similar, and have problems with the shortcuts, you can adjust the settings on your device. Check these instructions from Apple support about adjusting the settings.
If keys such as arrow or space won't work, it's because they conflict with iOS keyboard commands. If you want to change them, go to Settings → Accessibility → Keyboards → Full Keyboard Access → Commands on your iPhone/iPad. You can reset the commands that are the same with the Yousician shortcuts, by tapping the key and then tapping clear.
You can check the full list of shortcuts in the Game tab in-app.
