A rule in always all applications is: Moving + ALT-key pressed is a copy.
This works even in macOS' Finder, Powerpoint, all Adobe Apps and others.
Unfortunately, in Affinity Apps, it's not working as expected:
The user has to press the ALT Key BEFORE beginning to move. It should also be possible to press the ALT-key at any time, even while already moving. (as with the shift-key to keep axes).
And there's also a place, where the "moving+ALT-key=copy" does not work: In the Transform Palette:
The X-position is 20mm. If I add a "+15" behind the value and press ENTER, the object is moved correctly to X=35.
It should make a copy if I confirm with ALT-ENTER. (Works in Adobe Apps).
I also couldn't find a way to make multiple copys of objects. InDesign and Quark have a dialog for step-and-repeat. (# of copys, X- and Y-distance).
And last but not least, yould you add a "repeat last operation" menu-entry + shortcut? (Like InDesign and Illustrator)
When having moved or duplicated an object, using this function would repeat the last operation for the selected object.
PS: Same functions are missing in Affinity Designer.
Thanks in advance
