[Message part 1 (text/plain, inline)]

By default, mouse-wheel-(global-)text-scale increases or decreases the
text scale for every scroll event. I think it's a good idea to have an
option to buffer that (is that the right word?) so you can more easily
choose the text scale you want. I kept the default behavior intact.

Best,

Tyler

There was a typo.

Thanks, but isn't it better to control the amount of scaling by
changing the value of text-scale-mode-step instead?  Having to scroll
the wheel several clicks without any effect would be confusing, I
think.  And text-scale-mode-step is already a user variable that is
available for this purpose.  So maybe you should try decreasing the
default value to, say, 1.02, to see if that satisfies your needs.

For some trackpads, controlling how many 'clicks' to scroll is quite
difficult. The step size fixes the issue of scrolling too fast, but I
still have trouble choosing the exact text scale I want. My preference
is still for a larger step size and throttling scroll events.


Thanks,

Tyler

Sorry, I don't understand why you need to count clicks.  Typically
when users change the text scale, they just turn the wheel until the
size they get fits their needs.  Making text-scale-mode-step smaller
causes finer changes, so it's easier to be more precise in finding the
desired scale.

Can you explain how your proposal makes it easier than that, and why?

Sure, let me rephrase: for two-finger scrolling, it's hard to emit a
single scroll event. With a smaller step size it is easier to get it
close to the scale I want, but regardless of the step size, choosing an
exact text scale is difficult. This leads to buffers having slightly
different text scales.

If that's the problem, shouldn't that be handled by techniques we use
in precision-scrolling?

Could you expand on that?

Are you familiar with pixel-scroll-precision-mode?

Yes, but it's unclear which techniques you're referring to, or what is
lacking from the proposed behavior.

I refer to that mode's use of mwheel-coalesce-scroll-events and the
pixel-scroll-precision-* variables.  That uses underlying capabilities
of using high-precision mouse events which are new in Emacs 29.
