There are number of commands and actions you can execute in the game, these mostly control the GUI and where a button takes you, but there are other commands which perform specific actions like setting flags in the players profile.
Each command seems only to work at the appropriate stage ofthe game.

These commands are normally used in the onclick event of a button.

Profile Flags
The commands are used in the onclick event of a button, or in the oncomplete attribute of the <level> in the island.xml
oncomplete actions are executed when the level is "complete".
If the level is "normal" (ie. Pipe collecting Goos) the command is executed when the drop-down continue handle is clicked. ie before the scores are displayed.
If the level has any other type of endcondition, the command is executed when that condition is met.
unlockwogcorp : Set the WoG Corp Unlock Profile Flag (2)
This controls the enabled / disable state of the wogcorp_intact button in MapWorldView
undeletenow : Set the WoG Corp Destroyed Profile Flag (4)
See Special Levels - Undelete Pill for details.
NB: Executing this command in the "oncomplete" does work, however there is then a 20second delay before another button can be pressed.
unlockwhistle : Set the Whistle Found Profile Flag ( 8 )
The whistle becomes active immediately.
accepttermsandconditions : Set the Terms Accepted Profile Flag (16)
This unlocks the Deliverance level see Special Levels - Deliverance
Other Actions
restartlevelyes and restartlevelrightnow
These both appear to do the same thing, which is immediately restart / retry the level.
expandchapter4 : This command appears in the island4.xml as an oncomplete for the Hello World! level. However it does not appear in the game exe, and does nothing.
