cmd-c/x on High Sierra
How can I use a keyboard in a finder to perform the following actions without touching either a mouse or a touchpad:
cut (option is greyed out in edit, shortcut cmd-X not working either)
copy (sometimes I get a ding sound when trying to perform this action)
open a file (when pressing Enter - I can only rename the file instead of opening it - for me it's very counterintuitive)
will appreciate some help.
thanks.
