Layer mask issue

cmd + I works great.  Shift + delete does bring up the Fill dialog box, - attached.  I haven't assigned cmd+delete to any action, it works half the time and I even completely uninstalled photoshop and started from scratch.  Thanks for letting me know about cmd+I, it makes working so much quicker when the shortcuts work.

Just cmd-I, that way a »Reveal All«mask actually changes to a »Hide All«-Mask and moving the Layer will not result in unwanted reveals.

Could you have assigned the shortcut to something else (either in Photoshop or the OS or …)? 

Does shift-delete raise the Fill-dialog? 

Here is a screen grab of my desktop.  The mask would not fill with black by pressing cmd + delete on the top layer.  My work around is to apply a brush  stroke in the empty layer and then it will cmd + delete to fill.

Could you please post screenshots with the pertinent Panels (Toolbar, Layers, Channels, Options Bar, …) visible? 

Hey @mikes98032507,

I haven’t been able to reproduce your issue yet—I'm on a Windows machine though. When did this error start happening? Was it after a recent update? If possible, could you upload a short recording to show what’s going on? That would be super helpful.

Thanks, Alek
