You can edit a couple of text files for a quick change, in this example I have adjusted 2 screens to place more crosshair commands.

1. Moved two sections, "Viewmodel Preset" and "ClanTag" from the Game options screen to the Video Options screen.

2. Adjusted items and added new controls for the crosshairs.

Below is a full CVAR list from CS:GO.

Please see these pages for interesting commands... Player Commands. Server Commands.

Warning: When getting a list from the console you never get a accurate list. Some values that are "0.5" drop the ".5" and display as "0". Better to copy the command and place in console for an absolute accurate value.

Date of the compiled list below is - 23 Aug 2012

Crosshairs  and hud_showtargetid including a Command list also a cut and paste for your autoexec file.

 Crosshairs. There are two basic systems, Default and Classic. You can change these in the "Help and Options" - "Game Settings" menu "Crosshair Style"...

cl_crosshairstyle (5 choices)
"0" = Default	"1" = Default Static	"2" = Classic	"3" = Classic Dynamic	"4" = Classic Static
