Et bind is a combination of different variables and their values, keyboard key, and punctuation marks. They are good to set some action or actions on a single keyboard key, so no need to use lots of keys to do something more complex.
The definition of a bind in computer science: binding is the creation of a simple reference to something that is larger and more complicated and used frequently. The simple reference can be used instead of having to repeat the larger thing. A binding is such a reference.
/bind [key] “[command]”
A simple example: if in the game you want to assign a key to your primary weapon (two handed) and want it to be sure of that, you can set another variable for the same key which will show a small text on your screen at the same time. This code would look like this:
/bind 1 “weaponbank 3; echo PRIMARY WEAPON SELECTED”
