One of the standout mechanics of Switch Access is its scanning feature. This lets you scan through menus and options using your switch, which is perfect for people who have difficulty using the touchscreen. You can also use the auto-scan feature, which automatically scans through options for you! It's a total time-saver, and it makes using your device way more efficient.
Another cool feature is the key mapping option. This lets you customize which switches control which actions, so you can set it up to work however you want. You can even use multiple switches to perform complex actions, like taking a screenshot or opening the recent apps menu! It's super flexible, and you can customize it to fit your needs.
