Trasher is an extension for the Apple IIgs that adds a couple of handy features to the Finder. These features are particularly useful if you're also a Mac user (and even more so if you're using an Apple IIgs emulator on your Mac).
Trasher adds support for moving files to the Trash by pressing Command-Delete when files are selected. In addition, if you also have my SideClick contextual menu manager extension installed, it adds "Move to Trash" to the contextual menu for icons in the Finder, and also an "Empty Trash" option to the contextual menu on the Trash icon.
