Miriad includes a reasonably sophisticated command-line editor. The up- and down-arrow keys allow scrolling through the history of previous commands, and the left- and right-arrow keys allow cursor motion within a line. Pressing the TAB key causes an attempt to perform file-name completion. Various control keys allow extra editing. A summary is given in Table 2.1. For copious information, see the GNU Readline library manual.
