Mac Left/Right Scrolling Inverted setting

[mattjudson]

Describe the bug
Not sure if this can be fixed because mac natural scrolling left and right natively matches windows when natural scrolling is on, but When turning off "natural scrolling" in MAC OS to fix the up/down scrolling and sequencing in xlights to match the default of a PC works fine but then it also inverts the left and right scrolling... In windows Holding the Shift key and using the mouse wheel to scroll down it scrolls right under normal circumstances.... on a Mac it scrolls left after natrual scrolling is turned off to fix the up/down. Note: When I get on a Mac I have to turn off the Natural Scrolling setting to fix the up/down scrolling so that the mouse scroll wheel matches Windows where down scrolls down and not up however apparently The left and right behaviour on a mac gets changed as well.

Ultimately This may be more of a MAC OS quirk , where both left/right and up/down are ropped into the setting and It will just never be able to match because both up/down and left/right get inverted, but if possible Can xlights be configured to have an option for this or only to obey the up/down scrolling from natural scrolling and not to obey the left/right scrolling aspect in Mac OS when turning off the "Natural Scrolling" ?

This makes it very frustrating switching between my pc and mac when navigating left and right on a sequence timeline when holding the shift key

As it is a person either have to suffer with reverse up/down scrolling with natural scrolling turned on or reverse left/right scrolling with natrual scrolling turned off.

To Reproduce
Steps to reproduce the behavior:

1. Turn off Natrual scrolling in the Mac OS as shown in the screenshot
2. You can verify that in xlights scrolling down on a mouse wheel in xlights it goes down instead of up like it does in windows
3. zooming in on a sequence tineline and holding shift and scrolling up should scroll left and scrolling down should scroll right like it does in windows but this is reversed

Using a magic mouse, slide left/right goes L/R and using Shift reverses it. Seems fine to me.

Thanks. I don't have a magic mouse. I just use a standard small Dell mouse with a scroll wheel that i use with my Mac Laptop for travel. so it seems to only be probematic to mice with scroll wheels. I suppose I could get a magic mouse and try to get used to the virtual slide left/right scroll or click instead of the physical scroll wheel with holding shift like in windows.

You also just made me realize that holding the Shift key in xlights in the sequencer is reversing the scroll wheel behaviour as well as enables the left/right scroll ability in the sequencer....so its seems like a conflicting key binding in MAC OS vs xlights sequenceing tab. I cant seem to find a key binding setting in either MAC Settings or xLight Sequencer though for Shift and scroll wheel actions. When I go back to the layout view and hold shift to scroll left/right in the model/group list then left/right scrolling with scroll wheel works correctly with the scroll wheel down action going right and the scroll wheel up going left which is correct so it's only opposite in the sequencer behaviour.

I just also demonstrated the issue of 'shift' scroll wheel to move left and right along the time line. I have 2026.15 as well as a 2025.13 instance... the 2025 instance works as expected, the 2026.15 does NOT. :( My testing was on windows and Mac both... This non-scrolling using the 'shift'/scroll only moves right and will NOT move left and once at the end of the line, have to grab the slider to manually move it back.
