Trying to understand the Preset window... any help... please? :)

I've been using BetterTouch Tool for a few months now and whenever I want to add a new shortcut, I just add it and move on.
The thing is, I would like to backup my presets often, but when I go to the Preset window, I see 3 different preset names and each seems to host different "triggers" (I guess that's what it's called?). What I want is to:
1 - Have only 1 preset will everything on it, instead of 3, so I can quickly export it
2 - Understand what that window has, what each thing does, what happens when I import another preset (for example the PlugSearch option was a file shared by a developer from whom I bought an app from).
3 - How to transfer from one preset to another so I can delete the other 2 and only keep 1?

Thanks for your patience in advance :wink:
