Another input device productivity tip: Swap your right button and middle button's actions.
Why? The right-click action is not much used, and middle-click is much useful. And right button is much easier to press than pressing the mouse wheel.
The right-click almost always activates a context menu. For majority of people, that's mostly used in browser, and not very often.
The mouse wheel button by default does several more useful things in all major browsers:
If you have Microsoft mouse, its bundled software (IntelliPoint) can easily do that. I believe Logitech mouse also has bundled software that lets you swap easily.
Otherwise, on Windows, you can use AutoHotkey. Here's the AutoHotkey code to swap:
$RButton::MButton $MButton::RButton
You can also use AutoHotkey to change the actions for the 4th and 5th buttons. See: AutoHotkey Basics.
If you don't want to spend a hour to study AutoHotkey, use paypal button below, pay $2. In the comment field, put “swap mouse buttons”. I'll email you a utility that does that. (just run it, that's all). Make sure your email address is included and correct.
