P: bracket keys not changing brush size

Thank you! This worked for me.

O atalho do pincel nessa nova atualização não está aumentando e nem diminuindo com as teclas de atalho "[ ]". Fiz um teste mudei para a versão anterior, voltou ao normal, reiniciei minhas configurações, mas mesmo assim não aumenta ou diminui nesta nova atualização.

(The brush shortcut in this new update is not increasing or decreasing with the "[ ]" shortcut keys. I did a test and changed it to the previous version, it went back to normal, I reset my settings, but it still doesn't increase or decrease in this new update.)

1. PHOTOSHOP (BETA) V 25.11
2. Windows 11

How do you get to this page, please? Just happened to me when upgraded as well and I have over 300 images to process.

Hello,

I am currently using the Photoshop Beta and have encountered an issue where the square brackets [ and ] for adjusting brush size are not functioning. Here are the details of the problem:

• Photoshop Beta Version: [25.11.0]
• Operating System: [mac osx 14.5 (23F79)]
• Steps to Reproduce:
  1. Open a new or existing document in Photoshop Beta.
  2. Select any brush tool.
  3. Attempt to adjust the brush size using the [ and ] keys.
• Expected Behavior: The brush size should increase or decrease when using the [ and ] keys.
• Actual Behavior: The brush size does not change, and the square brackets have no effect.

I have checked my keyboard settings and confirmed that the keys are functioning correctly in other applications. This issue seems to be specific to the Photoshop Beta.

I would appreciate any assistance or guidance on resolving this problem. If additional information or troubleshooting steps are needed, please let me know.

Thank you for your attention to this matter.
