Hi Larry,

Clicking on a line of text, in order to cause a certain value to be restored, was borrowed from one of Max's scripts.

The "grow_shrink" default "b" exponent value of 0.306349... (an irrational number), is calculated from the Golden Ratio number (1+sqrt(5))/2, = about 1.618...,
also irrational, and yields the Golden Logarithmic spiral (within some decimal tolerance or approximation, because the decimals go on forever).
In the event the value of "grow_shrink" is changed by the user, clicking on the Click line of text, restores the "grow_shrink" value to 0.306349...

I agree that there could be some confusion about clicking on the text line.
Perhaps someone knows of a different control "button" which could be clicked on, placed next to the Click for Golden Spiral.
Maybe a "radio button"?
Another checkbox button does not seem quite right, because the checkbox check persists, unless script could be added to both the grow_shrink slider, and the grow_shrink entry slot, which would uncheck the checkbox, in the event some other value is chosen?

I do not know which new control button would be appropriate...
Maybe Michael would have a better idea...
Maybe a button could be named "here"? And have a different color?
Or the whole text line could become a "button", a different color in a rounded box.
Part of the htm or html code is ... onclick='growthslider.value=0.306349; moi.ui.fireUIEvent("growthslider");...Click for Golden Spiral...

So some augmentation of the .htm code would be nice...

So maybe all that needs to be added is a couple of "button" controls? And maybe a color change?

The onclick button needs to look like a button...
