Tagging in Legacy helps me keep track of projects and direct line ancestors. There are advanced tagging options for individuals and marriages.
In the image above on Joseph Thomas you can see that he is tagged on #1, #4 and #9 and in the marriage section there are not tags.
The image below shows what the advanced tagging window looks like. If you right click on the tags (see above image) the Advanced Tagging window will open.
My tags change often as I work on projects. Right now I am trying to figure out what Rutan's belong to my Alvah Rutan so they are all unlinked from my tree in Legacy and tagged on #8 so I can find them quickly. I have also been trying to clean up some messes in my database so I tagged everyone in my database on #9 and when I come across people tagged on #9 I will figure out what needs to be done and delete the tag once it has been taken care of; there are a few that don't need anything done so I just delete the tag. I also use tagging when I am creating search lists to help narrow down my people even more.
How do you use the tagging feature in Legacy??
