I think he means how to reset to defaults. If it's variables, you can use the
resetvars command. If it's actual options, then you can achieve this by deleting your
config.cfg and
init.cfg from the directory quin mentioned.
Be sure you back them up first in case you change your mind!
As far as what a bind is... You "bind" commands/vars to keys. So, "forward" is bound to W, or "action 0" (primary fire) is bound to MOUSE1
It doesn't just have to be single vars/commands, you can even bind keys to execute blocks of code as well :)
The syntax for binding is as follows:
- {l Code}: {l Select All Code}
bind <key> [<command>]
To unbind a key, use:
- {l Code}: {l Select All Code}
bind <the key to unbind> ""
Those are two quotes with no space.
Hope this helped! If you need any more help, please don't hesitate to ask :)
