After seeing Half-Life 2 being played with the Portal Gun by importing the maps into Portal's map folder, I wanted to do it myself. I got the maps to work properly, but when I use "impulse 101" to get the Portal Gun and HL2 weapons, I'm unable to switch weapons by using the 1, 2, 3, 4, etc. buttons, except for the weapon categories that have the shotgun or grenade/RPG/Bugbait in them. If I want to use weapons like the Portal Gun, Gravity Gun, or the crowbar, I have to use console commands. Is there a way to get weapon switching to work?

I believe Portal does not allow buttons 1-0 on the keyboard to work since there are only 2 weapons in the whole game (single/dual portal gun) and you are not meant to switch between them.
