Translations:Android Tutorial for DDNet 9.3.1/65/en
Firstly, you use the key, the key a and d can now zoom, and the mode switch key can now execute the "off.cfg". When you finish zooming, use the rctrl again, the key a and d can now make you move, and the key rctrl can now execute on.cfg. As you see, rctrl is considered as a mode switch key there, it can temporarily change the binding of other buttons and have the ability to reset them after using. This is similar to "bind rctrl+a", but mobile ddnet does not support this, so we have to make a small change.
