Keyboard shortcut problem

[Doc_Pit]

Often, I'm painting black on a white mask when, suddenly, I'm painting white on that mask.  Both chips (foreground/background) are white.  Obviously, I'm unconsciously hitting some key that is causing both chips to go white.  I do use alt + right click (the R-click programmed into my Wacom pen) to control pen size and hardness.  I have no idea what I'm doing to turn foreground and background color white.  It's driving me nuts!  Insight?

By using the ALT/Option key you are sampling the color. In this case the white of the mask and thereby changing the foreground color.

To change the brush size or settings via the contextual menu you need only right click and not ALT + Right Click

Hi!

How have you programmed your buttons on your Wacom tablet and pen? Is it possible that one of the buttons on the tablet or the pen is programmed to switch colors? Or, are you possibly turning the pen upside down which would cause the eraser tool to be activated when the other end of the pen (other than the nib) is being used?

What version of Photoshop and what version of Wacom are you working with?

D should set them to their defaults Black foreground  White background.

Thanks very much for the replies.  I don't have any buttons on the tablet programmed to "X" (switch colors). 

Regarding use of the alt key: I don't use the menu.  I use alt and drag ( On Windows, Alt+ Right Mouse -drag left right to decrease/ increasebrush size and up/down decrease/ increase brushhardness. )  But I'm guessing that D.A.R. is right: Somehow, I'm unconsciously screwing up that sequence so that I sample.  Thanks, again.

I use the same method to increase/decrease hardnesss and size. However on a Mac its a 2 key operation. Opt + Cntrl. I presume, if it follows most keyboard conventions and translations  then the Windows equivalent would be Alt + Ctrl and not simply the Alt key alone.
