SciTE is an awesome editor which I use on multiple computers. Instead of trying to keep track of my User.Properties files on each computer I’ve created a SciTE Home variable under my System settings.
This tells SciTE to use it for my default locations. If you set it up on each computer you use you won’t have to worry about having different configuration settings. While I predominately use it for AutoHotkey, I also show how you can setup importing other property files and configure the settings under languages. Just remember you’ll need a folder that is accessible across each computer (I use DropBox to keep mine synced)
Here’s a video walking through the process of creating a SciTE Home variable.
