Here is a list of the tagging metatags available out of the box; Shimmie extensions may provide other metatags:

• source=(*, none) eg -- using this metatag will ignore anything set in the "Source" box
  • source=https://example.com -- set source to https://example.com
  • source=none -- set source to NULL

Metatags can be followed by ":" rather than "=" if you prefer.
I.E: "source:https://example.com", "source=https://example.com" etc.

Some tagging metatags provided by extensions:

• Numeric Score
  • vote=(up, down, remove) -- vote, or remove your vote on an image
• Pools
  • pool=(PoolID, PoolTitle, lastcreated) -- add post to pool (if exists)
  • pool=(PoolID, PoolTitle, lastcreated):(PoolOrder) -- add post to pool (if exists) with set pool order
    • pool=50 -- add post to pool with ID of 50
    • pool=10:25 -- add post to pool with ID of 10 and with order 25
    • pool=This_is_a_Pool -- add post to pool with a title of "This is a Pool"
    • pool=lastcreated -- add post to the last pool the user created
