Here is a quick tip for binding keystrokes to access features that normally are not available in Wolfenstein Enemy Territory. First off, access the console by hitting the ~ key. Then type /bind <keystroke> [command] where keystroke is the key on your keyboard or mouse that you want to use to activate the command.
The two commands that I learned recently are throwingknife and playdead. The throwingknife command lets you do just that, throw knives at enemy players while playdead lays your character down on the ground and takes a wounded position.
If you have a 5 button mouse you can even bind the throwingknife and playdead command to your back and forward buttons. For example: /bind mouse5 playdead would make you play dead and come back “alive” when you hit the back button.
I realize most of you probably don’t play Wolfenstein Enemy Territory but I get the occasional Googler coming here looking for tips, so I hope this helps. For a complete list of commands try typing cmdlist in the console and then use the “Page Up” and “Page Down” keys to scroll through the list.
