Built‐in commands (cancel_my_transaction.do and cache.do) - jcmings/sn GitHub Wiki

If you've ever run into the dreaded infinite loop situation that's slowing down your instance, try typing /cancel_my_transaction.do into your filter navigator or URL (after .com, obviously). This will kill your transactions and force whatever background activity to cease.

Another helpful command is cache.do. This will clear your cache in your instance. Just like the command mentioned above, you can do this in your filter navigator or your URL. You'll notice in the screenshot below a reference to another custom command, powered by SNUtils.
