Here is a link to my templates on Github. You’ll need to copy the text into a text editor (e.g. Notepad ++ or Sublime), then save the file as templates.md in the “Pages” folder in the folder where your Logseq notes are stored.
It's worthwhile noting that I don't really use the in-built templates feature any more after incorporating a text expander into my workflow (I use aText, although there are a number of different options out there). I've included the video below.
Now the time taken to pull up the "/" menu, then find the template you're looking for may seem trivial, but if you're using them regularly, I can guarantee that you will be grateful for having a text expander workflow. It makes entering repeatable information an absolute breeze 🙂
