DUH!
We know! I know!
Have you heard about alias's? With this you can multiple commands to one key, and shorter.
Try this:
Type in console: alias tau give weapon_gauss
Now type: give tau
Voila, you get the Gauss cannon.
Another example:
Type in console: alias 1337 give_weapon_gauss;give item_suit; give item_longjump
Now type: give 1337
You'll now get 3 item at once.
Experiment with it.
