I reported the same issue on my HP laptop, using Windows 10. Other common key shortcuts, such as Ctrl & D for normal duplication, Page Up and Down to raise and lower objects, also do not work. This "issue" of common, normal keyboard functions, only has happened/does happen when I use version 1.1. No prior versions for me. I reported this weeks ago. (Also, I checked and changed out my keyboards, and no other software I use has this problem occuring. Only version 1.1 in Inkscape.)
