Discussion Overview

The discussion revolves around the functionality of the "Manipulate" slider in Mathematica, specifically addressing issues related to fine-tuning the slider using the ALT key. Participants explore the behavior of the slider across different operating systems and versions.

Discussion Character

  • Technical explanation, Debate/contested

Main Points Raised

  • One participant notes that holding the ALT key while dragging the slider causes it to jump to the left end, making fine-tuning difficult, particularly in the right half of the slider.
  • Another participant inquires about the operating system being used, suggesting that the issue may not be universal.
  • A participant confirms they are using the cloud version of Mathematica and experiences the same problem, indicating it may be a bug specific to the Wolfram Cloud.
  • There is a suggestion to contact Wolfram for a bug report regarding the issue.

Areas of Agreement / Disagreement

Participants generally agree that the issue exists in the cloud version of Mathematica, but there is uncertainty about whether it is a universal problem across all operating systems.

Contextual Notes

The discussion does not resolve the underlying cause of the slider behavior, and there are limitations in understanding whether the issue is specific to the cloud version or related to other factors.

TL;DR
I want to use the ALT key to slow down the effect of the slider in a "Manipulate" output. Unfortunately, pressing ALT sends the slider to the left end. So it's impossible to fine-tune around the right part of the slider.
It says here ...

https://reference.wolfram.com/language/tutorial/IntroductionToManipulate.html#498667553
[section : Initial Values and Labels]

...that you can fine-tune a "Manipulate" slider by holding down the ALT key while you drag the handle. This is indeed the case, but unfortunately, the ALT key causes the slider to jump immediately to the left end of the slider. Then, if I move the mouse all the way across the screen, I can just get it to cover half the slider's length in this fine mode.

This means that I can't do fine-tuning in the right half of the slider. I have tried setting the default value of the slider variable to a larger initial value. But even in that case, the "home" position of the slider in "slow" mode is always the left end.

Is there a way to fix this?

What is your OS? On my Mac, it works fine (meaning that pressing ALT doesn't move the slider).
 
I'm using the cloud version at wolframcloud.com

I have the same problem as you, so it appears to be a bug in the Wolfram Cloud. You'll have to contact Wolfram and make a bug report.
 
OK, thanks.
