I can't get a grip on the keyboard parameters in FSUIPC. I have taken one of my Axis and set it up to raise gear and lower it for the PMDG 737 NGX, easy enough. Then I read in the manual that you can assign "Key Presses" to an axis. So I setup the axis with 3 events. The top portion of the stroke to raise the gear going "up", the bottom portion to lower the gear going down the center portion to turn the gear off, going down. The gear off is done by key presses - CTRL + G. This is where I don't get it. The key press is set in "Parameters" under "Control sent went range entered" in "This side to send button controls" in "Axis Assignment" tab. In the "Advanced" manual there is a key parameter reference section that is a bit confusing to me. For "CTRL + G" I thought I needed The "parameter" 71 + 2, but it doesn't work. Anyone get how the parameters work, thanks.
