How to map mutliple keys to a button in Half Life 2/Team Fortress 2?

Solution 1:

You need an alias. Create a file called autoexec.cfg in your Steam\steamapps\YOUR_ALIAS_HERE\team fortress 2\tf\cfg and add the following:

//Rocket Jump
alias +rocketjump "+jump;+duck;wait;+attack"
alias -rocketjump "-jump;-attack;wait;wait;wait;-duck"
bind mouse2 "+rocketjump"

Change mouse2 to your desired key. You can do so much with scripting, this is just one example. Check out the TF2 Wiki for more.

Solution 2:

Simple.

in steam right-click on tf2, press "OPTIONS", click on Set Launch Options then type -console. Start TF2, press _`^~then type

alias +hop "+jump;+duck;wait;+attack"↵
