so first you're gonna open up the options menu and then click on the advanced option and click on enable developer console.

When you did that you have to press this key ` witch is located under the esc button on your keyboard.

this command is pretty simple it binds a command to one of your desired keys

for example bind k command

you can also unbind keys (note:if someone tells you to type in console unbindall do not do it it will just disable your movement)

for example unbind k

NOTE: this has been edited by me now and i hope its useful now.
so basicly you can see what key you binded to your keyboard

example: bind B zoom

it will bind that key to zoom in with the hl2 zoom feature
but if you forgot what some key does you can type this

bind k

it will display what you've binded to that key

this command is kinda complicated but it dosent work when you are trying to build something on servers (keep in mind you can always bind a key)

command: ent_setname a; ent_fire a enablegun 1; ent_fire enableradar 1

you will also need to give your vehicle the mounted gun

do this by holding the context menu(default button is c) and then hover you're cursor to a jeep or airboat and then go to bodygroups and click on the tau_cannon (for jeep) or weapon (for airboat)

this isn't very cool to do on servers because this will get you banned for doing this (there are some servers that allow you to prop kill but that's only for small props)

command: physgun_wheelspeed 99999

note:you cant build stuff with this type of speed so you are gonna need to turn it back to normal speed when you are gonna build stuff

normal speed is 10

this is probably binded by default so you don't need to bind a key for it

default key for zoom is b

command: bind <KEY> +zoom

this is useful for creating cinematics if you aren't very good with the camera

if you dont like the stuff on your side screen then there is a mod to remove it
