In Indigo, you can create a single macro command string (or any other field that sends a command string) that contains multiple data commands to send to the connected session. 

Each individual command in the string must be separated by a pipe character "|".

Examples:

• 1|2
  
• one|two|three|four|five
  

(To test your command, you can enter the entire command string on the command combo bar at the bottom of the terminal session.)

If you need to create a time delay between each command, you can add the internal pause command in between each data command. 

The syntax for the internal pause command is:   " :p:0000 "  where the 0000 represents the number of milliseconds to delay.

Examples:

• one|:p:2000|two
  
• one|:p:1000|two|:p:2000|three|:p:3000|four
  

(More information on the supported internal command can be found here in the online Indigo help guide.)

Please note, the Multi-Command feature must be enabled in the Session Properties, it is enabled by default.  You can also change the delimiter character from the pipe symbol to another character if needed.
