Get a grip on sensibility

[apocatarsis]

Synapse lets you assign a button to change the sensibility of the mouse. This would be neat!!
But I do not know the first thing about it

[drunkscientist]

so assuming you mean 'sensitivity' i found some relevant information but dont know enough about programming to do anything useful with it

I don't think we need to implement this at all since this exists for DPI change https://github.com/mbuesch/razer . Also you can call this app from naga_keypadmapper if you want to.

But that is super big! It should work without any more work using this project alone!

I was thinking of something like in here or here.

Something like adding a new option to mapping.txt like dpistep=-300 so you can bind a button to increase/decrease sensitivity. Instead of xdotool we culd use some xinput magic. I really think this would be neat!.

I was able to change the speed at which the pointer moves by modifying the ConstantDeceleration in the xorg config for the mouse. I think this can also be achieved through xset m [acceleration ratio] [acceleration threshold] (https://wiki.archlinux.org/index.php/Mouse_acceleration).

[apocatarsis]

I was thinking more of as in changing the mouse DPI, like you do with synapse on windows. I dont know if that would be equivalent, but my guess is not. Let me know if you find out!

There's a command to do this

xinput set-prop <device_id> "Coordinate Transformation Matrix" x 0 0 0 x 0 0 0 x

Replace X with a floating point number.

I can pull request to implement a way to increment or decrement sensitivity if needed, or you can simply use an environment variable to store the sensitivity between changes (probably better, makes app lighter).
