Debian 7 Wheezy: Unable to delete file with Delete button
You may experienced this situation when you first time installed Debian. By default, moving to trash keyboard shortcut is Ctrl+Del.
If you’re not used to that there is a way to change that to Del key.
If that doesn’t bother you or you used that combination before, you can leave it like that.
Applications > System Tools
and select dconf Editor
When it opens, navigate to:
org > gnome > desktop > interface
Now you should check option:
Note: Leave dconf Editor open
Open nautilus and make some file.
Click on that file to select it.
Now you need to choose Edit option in Nautilus
Hover Move to trash and press Delete key twice to change shortcut.
Uncheck can-change-accels in dconf Editor and exit.
Test if everything works, make a file and try to press Del key on your keyboard. If all works well, file should be moved to Trash.
