 * `$redirect-rule`: Similar to `$redirect`, but is only applied if it's already blocked by *another* entry or dynamic rule(set).
 * `@@||` + `$ghide`: Same as `@@||` + `$generichide`.
 * `@@` + `$cname`: Prevents another site from being strict-blocked if the domain shows up in its CNAME response. `$~cname`, and `$cname` for blocking, also exist, but are poorly documented.
+* `$queryprune`: Removes URL parameters, e.g. `$tracker=sitecampaignpage`. Assumes RegEx by default; add a `|` after the `=` to avoid assuming such.

+* `$removeparam`: Very similar to `$queryprune`, except that it assumes ordinary text by default and that RegEx is opt-in.
