Causes the block with cid=1234 to be embedded.   The edit or configure commands for most blocks will contain a cid=4321 sequence, that sequence is needed here.

Notes

• Embedded blocks are always in 'Preview Mode' even if the containing block is editable.
• Embedded blocks do not show titles
• Styles and visibility preferences are not honored in embedded blocks

Embeds social links. This is the same as {hd cid 1234} except that the cid is automatically set to be the most recently edited social media block that is showing horizontal links.

In most cases this will be the only social media block, but i the ambiguity is a problem use the {hd cid 1234} explicit specification

Reports days, hours, minutes until a date. The counter does not change while they watch, but it changes every time it is shown.  The embed sequence can be formatted with the usual font and boldness.

Example: " {hd time-until 12/25/2015} until Christmas."   becomes   "43 days and 16 hours until Christmas."

Behaves like time-until except that it counts time past the supplied date.

Causes a insertation of a HTML fragment that is replaced in rotation by other fragments.   Example:
   I am great    becomes
   I am cute     becomes
   I am a showoff
