P: Modifying/deleting Previous or Next Brush Keyboard Shortcut doesn't work correctly

I hope that others will chime in and vote...

@Jqqerry  Does MAC os reproduce such symptoms? I don't know because I'm a Windows user.
@PECourtejoie  Thank you for your suggestion. And your temporary measures didn't work for me. At least it worked for me to erase the preset.
But it's also a temporary measure (like the result of me erasing all the brush preset include default.)
Obviously this is a bug (because it doesn't work as expected), but it doesn't create a serious problem with Photoshop's experience, so I expect my thread to just disappear without interest. Haha..

Hello, the trick, for me, was to assign other functions to , and . in addition to previous and next brushes.

@PECourtejoie 

As I added above, I have already tried to assign different keys to previable and next brush for unlink.
And I posted a bug report because it didn't work.
And if you erase all the default presets of the brush, it will be disabled even if you press the key as expected, so it's called a bug.
Because I left the key blank in the first place, even if there is a preset for the brush, it should not work even if I press the key.  don't think Adobe will be interested in this. It's a very minor bug (That's why this bug has been going on for nearly five years, right?)

Hi, I was able to replicate, on a PC, even the [and ]  keys cannot be disabled in preferences. A restart does not change anything.

I was able to intervert [and ] with , and . so maybe you need to attribute another funtion to these keystrokes to "unlink" them from the next/previous brush.

Another related bug:

I was also able to use ` (accent grave, the alternate to Tilde) that is used to switch to the eraser tool with same settings, it was accepted, but ineffective as aKBSC.

Very funny bug. Based on the author's video, the bug could be reproduced by copying the movement as it is.
The < and > keys are assigned by default in Photoshop, and if there is a preset, it seems to be a bug that works even if you disable the key. I will test later to see if that bug can be reproduced on Mac.

let's make sure what i'm talking about this.
When I put up the thread, I thought someone could see it and write an answer like this.
"Then force another keyboard shortcut to preemptive and next brush so that the key does not work."

Actually, i already did it!. And even if you specify another shortcut, pressing <(,) or >(.) will work like a bug.
That's why I wrote the thread!

And just in case, i'll tell you. I've already done resetting tools, resetting preferences, and reinstalling Photoshop for many year!
And it's not just my problem because it's reproducible on all Windows 10 computers as well as my computer!
