Why Customize Mouse Buttons?
You come around a corridor only to find an opponent looking the
other direction or out a window. It's a perfect chance to sneak
up and whack them with the crowbar! You creep up behind them and
reach for the "1" key, but instead of a crowbar you hit the "q"
key. Or, worse, the "~" and bring down the console. Next thing you
know, you're dead.
If only there were a fast and reliable way to grab that crowbar
Well, if you have a mouse with more than two buttons, there is!
In the section below I'll show you how to bind mouse buttons to
Half-Life game actions such as "use the crowbar".
The standard Half-Life configuration assigns mouse buttons 1 and
2 to "fire" and "secondary fire", respectively. But three-button
mice have been common for years, and nowadays it's very common to
have five buttons plus a wheel. Don't let those buttons go to waste.
Use of the wheel is configured by default in current Half-Life versions,
but you have to do a little work to take advantage of mouse buttons
3, 4, and 5.
I currently use the Microsoft Intellimouse Optical shown above
and have been very pleased with it. Some sources incorrectly describe
this as a "2 button" mouse. If in doubt, check the part
number: D58-00002 is the 5-button mouse shown above.
My opinion is that the more-expensive Microsoft optical Intellimouse
Explorer is an inferior choice for game play. The Intellimouse
Explorer is an asymmetrical "right-handed" mouse (I've
never seen a left version) with buttons 4 and 5 both located on
its left-hand side, for operation by your right thumb.
