I'm wanting to customize one of the build in dialogs programitically so that if the user is on a certain dialog certain controls behave a certain way. While playing around with the "Wizard: Set Control Properties" script item to change the "Next" button on the last screen to "Install &Now! >>" I couldn't find a list of control IDs as this script item needs a specified ID to act on.

Here's my code I'm using to try and change the button (this is in the [User Interface] section right up to the point where we're about ready to call the progress dialog):

[ User Interface ]
! Wizard dialog definition(s)
Define Wizard Dialog "#1" (Welcome)
Define Wizard Dialog "#2" (Readme)
Define Wizard Dialog "#3" (License Agreement)
Define Wizard Dialog "#4" (Select Setup Types [Standard])
Define Wizard Dialog "#5" (Custom Install)
Define Wizard Dialog "#6" (Check Boxes) (%OPTFLAG%) -- Store Checkbox text in %otionstext1% and Response in %optflag%
Define Wizard Dialog "#7" (Select Install Folder) (%_SB_INSTALLDIR%)
Define Wizard Dialog "#8" (Select Program Folder) (%_SB_PROGRAMGROUP%)
Define Wizard Dialog "DLG_READYINST" (Ready to Install) ()

! The Wizard Loop displays the dialog screens that the user sees in the installation
Loop Wizard (Abort Dialog Active)
If %_SB_DIALOGID% Equals "6" Then
If %OPTFLAG% Does Not Equal "1" on Position "2" Then
Hide Wizard Dialog "#8"
Show Wizard Dialog "#8"
Set Text "Install &Now! >>" to ControlID "$NEXT_BUTTON$"

! Display progress dialog


Again the question of the day is "Where's the master list of built-in control IDs?"
