highlighting options(value change) without using touch view?

[Husleville]

Hey i'm wondering if you can help me out. My church has a korg triton pro 76 key but apparently the screen isn't responding when it is touched although everything on the screen can be seen. So i was wondering if you can still explore the keyboard without the touch screen capability. One particular problem/example i have is when u press the global button then hit the basic setup tab a list of functions come up however the first function which is the master tune is highlighted so you can change the value of it. My problem is scrolling down to the transpose function or any other function below in order to change its value. When i use the value knob, the dial, the +/- or the arrow buttons they all do the same thing and that is changing the value of the master tune and not scrolling down. I rarely get to use the keyboard so i cannot make various attemps to figure this out so i'll appreciate it if you can help. <<In>>
