When browsing through file context menu, I've noticed that I couldn't find a command to delete it. Only after examining each item, I found "Move to trash".

IMHO it's unintuitive. An user doesn't want to move a file/folder, but to remove it (the fact that there's an undo - a trash, shouldn't change the terminology). The term "move" misses what user wants to do.

Simple "Delete" would be *much easier to spot*, especially when the menu has many items (16 in my case). It would be simpler and it would be shorter.

When user enables permanent deleting in preferences, the term could be "Delete permanently".

Other information:
The issue was already raised many times before in some places
(e.g. http://www.mail-archive.com/usability@gnome.org/msg03430.html - see 4. "Move to Trash"
or http://ubuntuforums.org/showthread.php?t=1007979 - task "Search sample document from a specific option, delete and then restore it.")
but no action was taken.
