Lovely thing about Obsidian, once you start to type a tag with the # sign, and type a letter, you can see the tags that begin with that. Since, I may not remember the exact tag, I can remember the idea of it, and if one choice of first letter doesn’t work, I can continue to type the idea, and the tag usually appears in the list of choice of tags. I use keywords for discussion points and methods for my thesis. Thanks for sharing!
