Go Through Walls
In order to give your character the ability to move through walls, hit the "~" to bring up the command box and type in the word "noclip".
Auto Reload
If you want your character to reload after every shot, bring up the command box by hitting "~" and then typing in "+reload." In order for this cheat to work, you must be the host of the server. To turn off this cheat without exiting Counter-Strike, simply type "-reload" in the command box.
Auto Aim
The Auto Aim cheat will automatically direct a player's cross-hairs to the opponent's head. Therefore, a player with this cheat enabled simply has to shoot once (or twice depending on the gun) to kill an opponent. To enter this cheat, bring up the command box by hitting "~" and then type in "sv_aim."
Invisibility
The invisibility cheat will not allow other players to see you. However, it only works if you are the host of the server. To activate this cheat, bring up the command box by hitting "~" and then type in the word "notarget."
Bind Costumes
This bind (a way to program one key to perform several actions) will allow players to sync keys with certain costumers.
