Server messed up weapon selection system. How do I fix it?

I went to a zombie survival rp server and it had this wierd feature that got rid of the drop-down weapon selection feature of half-life. Now no matter which server I go to, whether I go to multiplayer or singleplayer, the drop-down weapon menu whenever you press a number is gone, it merely cycles through them now. How can I fix this?

Try going to:

Options>Keyboard>Advanced.

If “Enable Fast Weapon Switch” (Or something like that) is checked, un-check it.

It worked. :smiley: Thanks.
