For instance, I’m on Jury Duty in the US this week. Kinda a freebie but I still have to call in and input my “ID” number, birthday, and zip code before entering phone tree options to hear my summons status. So I saved a contact in my phone for the jury hotline with the main number, my Id number, birthday, zip code, and menu option numbers all separated by a comma. Now when I dial using the saved contact, it will automatically enter everything in and I don’t have to fumble around and spend unneeded time to hear if I have to report.
This can easily be adapted for any automated phone system that you call frequently although you’ll have the best results when you have to enter in a long account number like at a bank.

I believe a semi-colon means your phone waits to send the next string of numbers until you tell it to so you can still have everything queued up and just listen instead of trying to pre-program the timing
