If I were to send this file to a friend would it send it with the UDL or would I have to do that separately?

@Ekopalypse gave you the right answer. However, given the way you phrased that, and re-reading your original question, I think it might help you conceptually if you read this FAQ

To make it look the same to others as it does to you, they have to use the same UDL and more or less the same theme.
So you need to send it to them or make it publicly available somehow.
Here is described how to export and import UDLs.

Im sure this has been asked already but I couldnt find specifically what I was looking for. I want to save the style tokens I add to a doc so the next time I open it, everything is still color coded.

You’re right: it has been talked about, multiple times. I found this discussion which included a script for the PythonScript plugin, plus links to at least three other related topics. If you read that discussion, you will learn more about the scripting solution.

However, for yours, since I’m guessing that the keywords you want to highlight stay the same from time to time, and you probably want them highlighted even when the config for you game has been changed, I would suggest a UDL (“User Defined Language”). I know you said you’re “not coding anything” – but config files can be syntax highlighted just like programming languages or markup languages, and UDL is not limited to “coding”.

The UDL system allows 8 different keyword groups, so you could easily put your keywords into eight different colors. If your config file has a unique extension, you can just add that extension to the UDL, so it will automatically apply the UDL when you load the file. Otherwise, you can manually select Language > GameConfigFileUDLName to get it to do all the highlighting.

Using the UDL would probably be easier for you than trying to figure out how to use the scripting solution provided in that other discussion.

Good luck.
