I am going to write this as concisely as I possibly can. Really need help here.

TV model: Sony XBR65X900F

Background: At night time, the bright tv hurts everyone's eyes. So we like to change the picture mode to a custom one we have set up which makes it super dark. However, it is annoying to have to press ACTION MENU --> PICTURE ADJUSTMENTS --> PICTURE MODE --> <scroll to the picture mode we want> ENTER --> BACK,BACK,BACK

My primary goal: To change to a SPECIFIC picture mode on my Sony TV with the press of a single button on the remote, by remapping it with Button Mapper app.

Problem: I don't know what command Button Mapper needs to send to select a specific picture mode (or even toggle through them) in the Sony settings.

Questions: -Is my primary goal (above) or even my secondary goal (below) possible? -Do I need to use Pro version of Button Mapper to send shell commands? If so, what is syntax for Picture Mode toggle?

===== Backup Goal: if the primary goal is not possible because you can't go directly to a specific picture mode with a command to the TV, I'm willing to concede that the button could be used to TOGGLE through ALL picture modes instead.

EDIT 1: No, I am not interested in using the ambient light sensor to adjust the brightness because, number one it changes my color and brightness settings from what I want during daytime use and because number two it doesn't bring the brightness and contrast low enough on the TV at night time to make enough of a difference.
