The console window, or debug console, is StarCraft II's method for showing errors and debugging maps. To open it, use the tilde (~) key, which is just to the left of the 1 key. The currently known commands for it are:
- clear : Clear the console
- dump : Dump object members
- eval : Eval an expression
- help : Display this help
- set : Set a variable
- show : Show a variable
Simple enter the command and press enter. To close the debug console, just hit ~ again.
