Hi Andrew, welcome to the community 
With Text Blaze, you can change the settings for snippet insertion for each individual folder.
You can choose:
- Started by word break - snippets are triggered if preceded by a space
- Started & ended by word break - snippets are triggered if they are preceded and ended by a space
- Anywhere - snippets are triggered anywhere as long as the shortcut is typed
If you want to have similar shortcuts, I suggest adding different special characters in front of them, or just adding numbers at the end of them (like :ld1 :ld2 etc).
Though, if your shortcuts are ;ld and :ldd then you should be fine.
If you have any questions, please let me know.
