: Photoshop increase brush size shortcut I currently wish to use the shortcut to increase or decrease brush size in Photoshop by selecting a brush and option clicking then dragging to the left

@Bryan765

I noticed that that it wasn't working for me one time, and my mistake was that I was not doing the right clicking on the image canvas itself.

If not already doing so, try doing the "alt + right-click + drag" shortcut to resize the brush on the actual image canvas instead of on the blank space outside of it. This may seem obvious but it took me a while to figure out.

Downgrade previous gen Wacom driver: MacOSX 6.3.21-8 to resolve PS CC brush resize/hardness with Ctrl + Alt.

The same thing happened with me.

This is my way: open Edit/keyboard shortcuts and menus

In the keyboard shortcuts panel, choose Tools, at Eyedropper tools, delete everything you found there, I means EVERYTHING. AND ACCEPT/OK.

And it comes back to normal, now I can use Control + option, move mouse to left/ right to change th brush size.

Hope this will help

For Mac users:

Option + Right mouse button = brush size (left <-> right) & hardness (up <-> down)

Option + Left mouse button = Eyedropper tool

For Windows users:

Alt + Right mouse button = brush size (left <-> right) & hardness (up <-> down)

Alt + Left mouse button = Eyedropper tool
