Some of you might have noticed people with L3/R3 clan tags in Call Of Duty 4 - Modern Warefare.

Platform: Playstation 3.

Here is a very simple guide how to do it.. all you require is a USB Keyboard.

1. Have the keyboard connected to your playstation 3.
2. Go into Settings > Accessories > Keyboard language
3. Set your keyboard to "Dutch"
4. Go into call of duty and click on Clan tag.
5. Hold down "ALT 3 and then ALT 4"

You now have a L3/R3 clan tag.

This is the best and fastest way to do this, if you want other clan tags such as PS buttons, directional buttons, circle, triangle, etc.. you must know how to hex edit and it gets really complicated.
