Restoring the old Delete key behavior. This isn't my fix, and I've seen it on other blogs & articles but the last time I tried it would not work. This method did.
Stolen from the Arch forum
If it didn't work create an empty folder ~/.gnome2/accels & try again.Quick fix:
Run dconf-editor, and open:
org -> gnome -> desktop -> interface
Open nautilus, select any file/directory, then click "Edit" from menubar, and hover on "Move to Trash" menuitem.
While hovering, click on your delete key. The accel should change from "cntrl+del" to "del".
Make sure you have selected a file, else the "Move to Trash" menuitem will be greyed out.
I suggest you disable "can-change-accels" afterwards, to prevent accidental accel changes.
