As you may have seen in other posts, I am using OneNote as my main GTD tool, and have started coding up my own extensions for the things that are missing. Just a few macros make OneNote much more useful! I should probably write up my current BKMs - but that is NOT this post. This post is about using tags as part of a GTD system. I seek advice from others with regards to patterns of tag usage, etc. You may have experience with OneNote tags - I'm listening! You may have experience with tags or labels in other GTD packages - I am listening (especially if the concepts are easy to code). You may have experience with DIY (Do It Yourself) tags, in OneNote or other systems - e.g. several of you have recommended ignoring the rather limited tag systems of OneNote (and EverNote, and...) and just using text tag conventions, like #HashTags, @PeopleTags. Heck, you may have a system for tagging items in a paper GTD system (Post-It Notes and page flags, perhaps?) BRIEFLY: what tags do you use in your GTD system? I'll post some of my thoughts in followup posts. I welcome better suggestions. --- Because I blather on, let me cut to the chase: I have been using the One Note "To Do" tag, but inconsistently. I don't want to use many other tags or symbols, because they may disappear. I have code to do various tag searches. The most useful thing I seem to be able to do with tags is enter/capture pages initially untagged As part of weekly or other review search for pages THAT HAVE NO TAG - specifically, no tag on the page title process such pages during the review sometimes applying [To Do] tags, creating [To Do] lists * apply a tag [GTD-PROCESSED] to the page title - so that the page does not atuirn up in other review searches (unless I really want it to) Note *: although I want to like To Do tags and checklists, I find OneNote's search facilities rather limited and less than useful. And I must admit that I am not quite sure what I want them to be. In part, I am posting this thread to try to ask people "What would you call a tag that you apply to a page or item to say that it has been processed into your GTD system, and should be ramified into next action lists, projects, reference, etc.?" [GTD-Processed] is the best I have come up with Or [GTD-incorporated]? Also, what emoji-like symbol would you use as a graphic indication that an item has been placed into your GTD system?
