Most applications that offer a tabbed viewing experience use the Control+T keyboard shortcut to create a new tab (firefox is probably the most frequently used one). However there are occasions where the focus is on a desktop window with a legitimate file (or worse, set of files) selected; in these occasions, hitting Control+T sends the selected files to Trash, which is quite frustrating.

Granted, the files can be easily recovered from Trash and the keyboard shortcut can be changed by the user after installation, but still, this is frustrating.

I'd suggest changing the default "Send to Trash" shortcut to "Alt+T", or deactivate it completely (the good old Delete button can do the same trick just fine).
