Right-click on an empty portion of your CommandManager, select Customize (near the bottom of the drop-down), then the Keyboard tab, to set hot keys, but I don't think there is an option for jogging dimension lines. I typed "Jog" in the Search box and it didn't show up.
The macros worked in 2012 sp5. I ended up having to make new macro buttons and assigning a hot key to each button.
Yes I could not find the correct jog command either.
Thanks to both for the help.
