How to pause sequence until after user input

[davinci7]

I am totally new to Macroscheduler and I just need it to guide a user through a series of tasks for processing data.

I can use the camera recording facility to record the series of tasks with no problems, but I need for the sequence to stop at certain places so the user can input the data to be processed. At each point where the script stops waiting for the user to input the data I need messages to pop up telling them what to do next.
So basically I need to know:
(a) how to stop the sequence until the user responds (by taking the next step such as adding text and hitting enter in a search field or selects text ready to be copied in next step) and then have it automatically continue.
(b) pop up a message telling the user what to do when the sequence pauses.
