P: alt+right click drag resize opacity lock

This is the single biggest issue for me in PS, as a professional digital painter. This issue (almost) alone has nosedived my opinion of Adobe.

I have to keep an eye PERMANENTLY, as in every few seconds, on the opacity box while I'm painting. Its no different to driving a car and having to check the fuel gauge every few heartbeats. 

Its insane.

It's frankly just baffling that this is still not fixed in Photoshop.

Please add this Adobe!  

Yes it is. Maybe they are developping some AI which would keep it locked for the user.

I can't believe that after all these years this is the only viable solution.

Thank you very much for this "hack". Whatever drawbacks it might have, at least I don't have to worry about painting, or worse, erasing with 99% opacity. I wish I new about this years ago.

This is hacky but here's what I use for Autohotkey to resize my brush and keep opacity at 100. The downside is opacity will ALWAYS go to 100 after sizing the brush using the shortcut. 

You can see that I'm overriding "d" key to resize my bush. So when I press "d" I have Auto Hot Key send alt and right click to photoshop instead.  Note that this works as long as you drag WITHOUT pressing the pen on the screen. Otherwise, I get an eyedropper.

You can change d out for whatever key you want to listen to. The part of the code that is actually setting opacity back to 100 after I change brush size are the Send{0 down} and Send{0 up}.

$d::

Send {alt down}{Click,down,right}

KeyWait d

Send {alt up}{Click,up,right}

Send {0 down}
Send {0 up}
Send {0 down}
Send {0 up}
Send {0 down}
Send {0 up}

return

update: sadly upon further usage i found instances where it didn't work properly and still accidentally changed the opacity, also the that code is not quite right, as it locks horizontally just by pressing alt, which would also be the colorpick, so i'm sorry it's not really a solution after all, tho aoutohotkey is still a nice tool

found a workaround:

1. install AutoHotkey (free open source good stuff)

2. wherever you want click New -> AutoHotkey script

3. copy in this below the text already there: 

~Alt::
MouseGetPoS,,Y
While (GetKeyState("Alt","RButton"))
{
MouseGetPoS,X,Y2
If (Y2 != Y)
MouseMove,%X%,%Y%,0
}
Return

4. save and run

it makes the dispalyed cursor jump around a bit with stylus when i do the resizing, but the actual sizing is smooth and and works for me 🙂 (i also remapped the windows key to mouserightclick with it autohotkey, so i can resize with win+alt+drag, if u wana do that too, make another file, and copy in LWin::RButton, save and run)
