Mint
Nemo
The "accels" file for Nemo when installed with the method linked to above is located at: ~/.gnome2/accels/nemo. The two files, ~/.config/nautilus/accels and ~/.gnome2/accels/nemo are very close to the same.
The reason why I desperately wanted to find how to edit keyboard-shortcuts was cause I HATE the default for focusing on the location-bar which is Ctrl + L. Practically every other application you can think of (e.g. Windows Explorer, Internet Explorer, Chrome, Firefox... list goes on) that has an "address bar" places focus there using the Alt+D combination.
Editing the following line in either of the "accel" files did the trick for me (make sure you remove the semi-colon, too):
From:
- (gtk_accel_path "<Actions>/ShellActions/Edit Location" "<Primary>L")
To:
(gtk_accel_path "<Actions>/ShellActions/Edit Location" "<Alt>d")
mkdir ~/accels vi ~/accels/nemo (gtk_accel_path "<Actions>/ShellActions/Edit Location" "<Alt>d")
Restart X
