I talked a bit about it in an earlier post.
Under the yellow text that you have in your screenshot, to the right of the blue chevron/arrow is where you type in your command.
The base command for any cheats in sugarcube is: SugarCube.State.active.variables.
After the dot you can type in whatever you like or scroll down through the list of suggested results. If you use the arrow keys to move up or down through the suggested results you can hit enter. If your command has a value, it should show that.

Here you can see that the seduction level is 100, which is max. If you want to change it, you can type in SugarCube.State.active.variables.player.seduction = 90 to set it to 90.
You can find this value yourself if you do as I described earlier. Type in "SugarCube.State.active.variables." and then use the arrow keys to look around, or type in what you believe you are looking for. Like you could search for Travis, rather than the player.

and see if there's anything you want to change, like obedience.

I hope this explains it.
