How do I make Microsoft Arc Touch Mouse middle-click on single touch?
I've just got my Arc Touch Mouse. It has a touch panel instead of the wheel.
By default you can scroll by swiping your finger on the touch panel. Tapping ends of the panel sends Page Up and Page Down and double tapping in the middle of the panel acts as middle click.
The last one is irritating. I use middle click quite often and I don't like that I have to double tap specific area for a single click, especially when I want to click multiple times in a row. I know that I can disable Page Up/Down in Microsoft Mouse and Keyboard Center, but it won't let me to configure single tap for middle click.
Googling yielded nothing useful. I don't find AHK workaround comfortable.
Is it possible to enable single tap middle click, preferably enable entire touch surface? Please note that I'm talking about MS Arc Touch Mouse, not MS Touch Mouse (which doesn't have middle button at all). This is the one I have:
Clarification, because I'm getting a lot of answers about remapping buttons:
Remapping is possible with the software that Microsoft provides. The problem is that for the computer to detect middle click, you have to double tap the touch panel on mouse. Computer doesn't seem to even be aware of single taps.
TL;DR: By default, to middle-click you have to tap twice. I want to tap once.
It is probably too late to answer five years after asking... There is an option now that is documented and supported by MS to simulate a standard middle click with one tap using Three Finger Click. Not sure it was an option that times. Also not sure it is much more comfortable to perform a single tap with three finger rather than double tap anything. But hope it helps those who stumble upon this answer. It just works and supported.
All you need for this is two following steps (no reboot):
- Download and install Mouse and Keyboard Center of MS
- Set Three Finger Click to Middle-click (as it is disabled by default)
I've found the answer here in the forum post of 2018 in MS Community.
This is how this setting looks like: 
I don't have an arc mouse, so I can't do this myself, but I would use some kind of listener hook to find what input is passed from the driver when the "single" middle click you are looking to use is pressed. You could try looking at event viewer (search for event viewer after pressing the windows key) as you press the middle mouse, or try looking at code generated by Microsoft IntelliPoint's macro record program. XMBC has a built in listener (buttons are highlighted yellow when pressed), but it only listens for a standard set of buttons, so I'm guessing that the single middle click doesn't register there.
If it were me, I would start a keyboard/mouse hook script in AHK, do a single middle mouse "click", then view the key history to see what input is being mapped. Use this AHK webpage (scroll all the way down to the Special Keys section) for a tutorial on how to do that.
Making the remapping script is straightforward - I would link an example but my currently low rep on this site prevents that at present. The first result in a google search for "AHK mapping mouse as keyboard" without quotes should get you there.
Another possible workaround is to make a script that maps a keyboard button you don't use often to "middle mouse click" and use that script when you use programs that require a middle mouse click for navigation.
Let me know if you need help making an AHK script, or you can find many examples of such a script via Google search.
If I remember correctly from my lost arc touch mouse, you only need to single-tap for the page up and down
if this is true, you can use AHK to pass a middle click and I believe nullify the original page up/down key-press, I haven't used AHK for a while.
one AHK script that may help you with that is the middle click simulator here : AHK Mouse Wheel Emulator
If I remember incorrectly, you can use the precompiled script to use both left and right click to middle click
in my opinion, it was a design flaw of Microsoft's mouse and software
