I've made an AppleScript that will delete all tags on the selected entry. This helps to quickly clean an entry up, so you can start over with it.
tell application "TaskPaper"
tell front document
tell selected entry
delete every tag
end tell
end tell
end tell
You can check out the script here. Enjoy!
