I'm running CS5 version 12.0.4 on a 2011 MacBook Air and the brushes do not work when resized between approx 300 - 650 in size. I don't know if this is a bug but the issue occurs in Lightroom as well. Please advise when an update will be issued to fix this. The software is pretty much useless to me with this issue affecting it.

Ah, now I understand. I'm sorry. I didn't follow what you were saying before. You're talking about Accelerator keys and you're correct. This was NOT removed on purpose and I've logged a bug to fix it. This problem appears to have been created with 19.1 and it's Windows only.
Sorry for the headache and we'll get it fixed ASAP.
