One caveat that I haven't been able to figure out yet is that, when using a custom cursor, it is used for all cursor functions i.e. no resizing cursors, no I-beam, etc.

i was afraid of that. i think that makes this cursor changing feature not so useful.
it *might* still be a good idea if one instead could trigger a windows-cursor-theme change, to change entire sets of cursors.

otherwise i suggest that it would be more useful to use a different mechanism besides cursor change to indicate the change in acceleration, like background desktop color.

in fact, given that the goal is to toggle back and forth acceleration for high precision uses (like in a graphics program), it would seem to me highly likely that the graphics program is going to have its own custom cursors in use (like paintbrush cursor, etc.) so the whole cursor changing idea is not going to cut it.

i think the idea of toggling mouse acceleration is a great one.. i'm not really sure you NEED a visual indicator about it.. it's going to be pretty obvious.  though i can imagine a separate idea for a docked bar on the screen showing various cursor related info (like acceleration, etc), color under cursor, etc. might be useful to some.

You can't do it directly with MAT, but you can easily with a couple of AHK hotkeys set up like this:

~^!+LButton:: Run, C:\path\to\MouseAccelToggler.exe accel=on speed=20 cursor="C:\path\to\cursor.cur"
~^!+LButton Up:: Run, C:\path\to\MouseAccelToggler.exe accel=off speed=10 cursor="Default"

This will let you use ctrl-alt-shift-left mouse button down to do one thing and another when releasing it.

Yeah...but I don't see how this will help you since you can't do much with the LMB held down, right?  In other words, you may want to change the LMB to a key or something.

Great to hear.  I'll promote that test build to a full release.  Thanks for the feedback.

i've realised that using the middle mouse button to control acceleration isn't that clever - there are other programs that can use the middle mouse button; silly of me to forget that.

so, if anyone is interested i've changed things to middle + right buttons (together) to accelerate.

keeping the return to default speed set at middle button release only (instead of middle + right button release), appears to have the extra benefit of acting like a toggle - so you can keep locked into acceleration mode until you just hit the middle mouse button again (the middle release obviously triggered the MButton Up action).

If you want to keep things so that only acceleration works when middle and right buttons are held down then change the 2nd line from "MButton Up" to "MButton & RButton Up"

MButton & RButton:: Run, "C:\Program Files\MouseAccelToggler\MouseAccelToggler.exe" accel=on speed=20 cursor="C:\Program Files\MouseAccelToggler\cursor large red.cur"
MButton Up:: Run, "C:\Program Files\MouseAccelToggler\MouseAccelToggler.exe" accel=off speed=10 cursor="Default"

I got this app and it seemed simple and great, but while the toggling works fine between the states, the acceleration-enabled state handles waay differently from what it was before using this app. I don't like it and am looking for ways to return it to the Windows (7) defaults, but it seems to have messed up some internal acceleration related values that Windows doesn't even let you access from the control panel.

I know I'm a bit late to the party here, but since there seem to be some actual value-based settings that need to be set instead of "just" toggling it, it could be nice to expose them with command line options, like the base speed.

Hi guys! I'm sorry for the noob question but I am really frustrated. I downloaded MouseAccelToggler.exe, extracted it, and ran it and got the popup. That's all good... But I can't get it to actually do anything. I realize it needs "- parameters" but I CANNOT get my windows to give it -params.

I have tried renaming MouseAccelToggler.exe to MouseAccelToggler.exe -speed=18 but that doesn't work because it changes from an exe file to one that windows doesn't recognize so it will not launch.

I have tried creating a shortcut and changing the target to "C:\Users\Alan\Desktop\MouseAccelToggler\-speed=18 MouseAccelToggler.exe" -speed=18

Then it says the following variable name contains an illegal character ARG_-speed the current thread will exit.

I've tried changing Start In to including a -speed=18 on the end, and that didn't work either.

Please tell me how, specifically, to just make this change thing work, as its the only program I've been able to find that will fix my problem. Thankyou

That did the trick. Thanks very much

Bump to Skwire: I recently installed Windows 10, and this program works fine on it. I use it to flip between a mouse and a wireless touchpad regularly. Works as well as ever.

What's interesting about MAT (don't know if I mentioned this earlier in the thread) is that it--and thus the Windows registry as well--offers a slightly finer-grained control over mouse speed than the control panel applet. The sweet spot for my mouse is actually between two of the ticks in the applet! So I can ditch the heavy Logitech application that I'd otherwise need to install and have continually running in the background.

So yeah, I've been using the two projects you've made for me: this, and Anuran, for going on a decade now. Thanks!
