The most common shell operations involve selecting files, opening files or running programs, dragging filenames to copy or move files, and deleting files. A pointer-based interface serves all such operations well. Therefore, the pen should behave as a pointer in the shell. Tapping or dragging a rectangular marquee should select files, double-tapping should open files, and dragging should copy or move files. The shell can provide deletion services on selected files either through a "delete" option in a menu or by handling a cut gesture.
