Keyboard Shortcut for Duplicate Drawing?

I cannot find the keyboard shortcut for Duplicate Drawing command by itself. There is a shortcut for ‘Duplicate Drawing and Add Keyframe’, but I don’t need to add a keyframe! I just need to duplicate the drawing, as the same as the Timeline command button “duplicate drawing”. It is such a basic function…
I know that there is a way to edit the Shortcuts.xml file, but I don’t know how it’s done.
Any suggestions? thanks…

Alt + Shift + D

So strange - last time I tried it tried to add a new layer instead… maybe I was too tired already and pressed the wrong buttons :slight_smile:
thanks!
