Additional game parameters
From Valve Developer Community
The Hammer Run Map dialog
Parameters entered into this field let you specify some game parameters which define how the game will be run.
For example, some typical settings:
-dev -console -sw +sv_lan 1
This would start your game in developer mode, activate the developer console, in windowed mode, and in LAN multiplayer mode.
