There seems to be a problem with the Copy command in 9.1.1.8 . I've reduced this to the simplest case I can identify that fails. If the command
copy DUPLICATE WHENEXISTS=rename AS _New.txt
is assigned to a key in 9.1.1.7, pressing the key with a file selected makes a copy of the file named _New.txt (assuming a file with that name does not already exist in the directory).
If the same key is used in 9.1.1.8, nothing happens.
It may also be worth noting that if the key is defined as
copy DUPLICATE WHENEXISTS=rename AS _New.txt
copy
both commands execute though the first one seems to not run until the destination for the second is specified Select Destination Folder dialog (only one file display present).
