Hot key for switching from BG to FG color

[MichaelJ57A]

My online classes are suggesting the D key except it's not working in the latest upgrade in PS CC 19.1.6

leaving the cursor on this section a popup shows that it's the X key to do this. What other changes have been made because this is going to be confusing trying to navigate the tutorials if everything is different now.

I'm using a MacBook Pro Mojave 10.14 is the OS

Under Windows 10, it's working the same as it always has: D set the default colors (Black and White), and X swaps them. What is the context of your online class saying to use the D key for?

Beginning Photoshop. learning the tools, . So, then this is how it's been in Windows and I'm on a Mac.

Thank you.

I learned on a Mac (a loooooong time ago), and it's always been like this.

That the D key is what switches between FG to BG? Hitting the D key doesn't do a thing unless there's an additional key to do this. placing the cursor on this section shows its now  the X key.

It's ALWAYS been the X key. D key has ALWAYS been default black and white.Both Mac and Windows.

You might double-check what your online classes are teaching. They should be teaching that D sets default foreground/background colors, and X swaps them, because that’s how every Mac and Windows version of Photoshop (going back almost 30 years) works. You can verify all of this by choosing Edit > Keyboard Shortcuts, and in the Shortcuts For menu, choose Tools. Scroll down to the listings for the shortcuts for Default Foreground/Background Colors with a D shortcut and Switch Foreground/Background Colors with an X shortcut. You can change them if you want, but those are the historical defaults.

Photoshop students are taught that an easy way to remember how the keys work is:

D stands for set Default foreground/background colors (black/white).

X stands for eXchange them.

Thank you for the responses. The tutorial I was following I suppose figures we already know something and this isn't the case.

This is copied from where I was having issues: "Now press the D key. Pressing D sets the foreground/background colors (found at the bottom of the toolbar) to Photoshop's default of black foreground, white background. We want black in the foreground so we can paint with it."

And this just was not happening till I found leaving the cursor on that section like in the screen capture I showed it stating X being the key to switch.
