You can assign comment macros to be executed when a show file is launched. Comment macros can be used to automate a variety of tasks such as recalling views or changing pages. Startup comment macros are assigned in the Misc pane of the User Preferences window:
Setup → Preferences → Misc
For details of the macro syntax, see Macros.
Startup macros only execute when the show file is initially launched. Any consoles joining a network show will not execute the startup macro.
