In Harmony terms the word "delay" refers to the four types that jlet referred you to.
Your use of the word is different which is why I misunderstood and said this was unusual.
The restriction to five commands and no delays in a sequence is a disadvantage.
However, the examples you give are really not part of the Harmony method.
The series of commands they require need to be sent manually, not automatically in a Sequence.

Well I'm doing them quite well in sequence using the ghost devices to generate the delays needed. It's a so so work around for now.

And guys thanks for the help.

Note that you can teach a short sequence as a single command name using the learning feature in RAW mode. Then you can use that learnt command in the activity sequence. However, your timing must be consistent when teaching a sequence in RAW mode, because it will ask you to repeat it for confirmation. Thus, it's a lot easier teaching a sequence in RAW mode from another learning remote.

Did not try that. I will with a pronto and let you know.
