You would definitely have that level of control. These signals don't map to your inner monologue but they can pick up your intention to physically do something. So if you think LEFT, you can move the selector on the keyboard to the next key to the left. And if you think CLICK, you can trigger a click. But you are focusing on asking your hand to physically make that click. Which your hand can't do obviously, but they can track those neurons to simulate the action for you.
