Another useful function is the DELAY instruction. You can instruct the
macro program to wait before executing the next keystroke.
SFED8248.COM displays the codes that you can use for various delays.
For example:
[86] - wait for 10 seconds before executing next keystroke
[88] - wait for 1 minute before executing next keystroke
[26]A[90][86][26]B[90] means ALT-A, wait 10 seconds, ALT-B
