DSDPlus Hot Keys For AirSpy Gain?

[CanesFan95]

AirSpys have 3 different gain settings. Is there a keyboard shortcut that turns 'em up and down? Thanks.

Oh crap, right there.

Say, what's the difference between "LNA, "mixer", and "VGA"? I seem to have a weird issue where I see a tall white spike on the spectrum and click on it but then there's no signal. Like there's fake signals if the gain is too high. Other times if I use the left and right arrow keys and slowly step through the band, I'll see more fake signals that move the wrong way.
