DO version 9.1.1.7.3307.x64, Vista.
I used to have Alt+D setup to highlight/activate the location/path/address textbox with breadcrumbs. However, I hate the breadcrumbs concept, so I toyed around in the commands menu and removed the breadcrumbs path field, and instead inserted a regular path field.
Now I just can't find anywhere to map a key to activating the path field .
