Linux – “Shake to locate cursor” feature

It is a complicated thing, taking into account the time domain, the infinite possibilities for an acceleration (or velocity) curve, framerate- or delay-independent behavior, etc.

Matching behavior with closed-source OS'es or drivers is nigh-impossible, but X.org provides you with ample choices for your taste, provided you take the time to read the documentation or the source.

Non-accelerated behavior (flat acceleration curve, linear velocity curve, linear mouse response or N pixels per 1mm of movement) is the only truly universal, easy-to-adapt and easy-to-adopt behavior. Ironically, it's also what most systems lack or make very hard to get. (See this open question, for example.)

Assuming you want linear response, I'll direct you back at the question you've linked.

The feature you are talking about is called "Auto-Scrolling". It lets you press and hold the middle mouse button and move your mouse to scroll smoothly. In Linux, the default behavior for this action (pressing middle mouse button) is generally pasting text.

However, there is a preference setting in Firefox and an extension available for Chrome/Chromium which would let you use the middle mouse button for scrolling and activate this feature.

Firefox

• Open the "Options" tab: "≡" (Open menu) → "Options".

• Navigate to "General" (it should open to "General" by default).

• Scroll down to "Browsing".  Under "Browsing", you will find the "Use autoscrolling" option. Put a check mark beside this to activate this functionality in Firefox.

  Or just search for "autoscrolling" using the search bar.

In older versions of Firefox: "Edit" → "Preferences" → "Advanced" → "General" → "Browsing" → "User autoscrolling".  Click on the below for a larger image.

    

Chrome/Chromium

For Chrome/Chromium we can use an Extension called "AutoScroll" (from kaescripts.blogspot.com).

• Go to this link on Chrome Web Store (obviously using Chrome/Chromium).

• Click on the button labeled "+ ADD TO CHROME" to install this extension.

  

• Click on "Add" in the Confirmation Dialog Box.

Other Applications

As far as other applications are concerned, I haven't yet found a solution for them. Anyways, it's the tall webpages that create most of the problems for which both Firefox and Chrome/Chromium have a solution.
