How to enter commands and change variables?
Whatever you wish to do with the console, always put a backslash or slash (\ or /) in front of what you type. Otherwise Quake3 will handle your entered text as a chat message. To execute a command, simply enter the command and press enter. To change the value of a variable, enter the variable name followed by a space and the new value. When you hit enter the new value will be assigned to the variable. If you want to see what the current and default values of a certain variable are, enter the variable name without any value behind it and hit enter. The console will now show the current and default values. Certain variables however will not show any immediate change. Mostly variables beginning with r_ (which are related to video settings) need a restart of the render system to be applied. To reset the render system enter vid_restart. If a variable value that needs a restart of something, you will see the pending value as “latched” when you only enter the variables name.
