Opacity/flow shortcuts switching when turning on airbrush effect

[EricJ32]

Photoshop v26.9.0 on Mac OS Sequoia 15.6

Under regular conditions, when the brush tool (B) is active, pressing 1 on the keyboard sets the brush opacity to 10%, and pressing shift-1 sets the brush flow to 10%.

Once you click the "Enable airbrush-style build-up effects" button, these keyboard shortcuts switch so shift-1 affects the opacity and 1 affects the flow.

Brush Tool Settings Troubleshooting

I was experiencing this issue previously so uninstalled and reinstalled Photoshop without any of my previous settings, and it was only when configuring my brush settings again that I discovered this as the cause of the issue.

Incredibly frustrating, please fix!

Hey, @EricJ32. Welcome to the Photoshop community. I'll clarify this for you. 

This has been the expected behavior since years. These changes happen when you switch to Airbrush Mode, the feature being a mode, changes how the shortcuts function.

I hope this helps. Thanks!
