Hope I get this right:
I use a free tool called "Spark" that lets you do chains of keypresses. I created a script/keychain, that does press OPT+APPLE+R, 1, <TAB>, 0, <TAB>, 0, <ENTER>. Bound it on Alt+Apple+D, lets me dup without altering the shourtcut too much.
This works for a lot of things, if you find avaible keyboardshortcuts left.
