A command line that extends into the rightmost column can be scrolled horizontally.<br />

If you try to move the cursor beyond the edge of the window, the line is scrolled to<br />

approximately center the cursor in the window. The second last column displays a<br />

character marking a scrollable line: < indicates extra data off the left, > indicates<br />

extra data off the right, and * indicates extra data off both sides.<br />

emacs/gmacs Editing Mode<br />

When the emacs/gmacs editing mode has been enabled, ordinary printable<br />

characters from the keyboard are entered in the command line and echoed. Various<br />

control characters introduce command sequences for such things as moving the<br />

cursor, scrolling through the command history, and modifying the current command.<br />

The only difference between emacs and gmacs is in the handling of Ctrl-T. (See<br />

the description of Ctrl-T on 579.)<br />

The command sequences recognized are listed in functional groups. The notation<br />

Meta– represents EscK, followed by the letter. The terminology is historical. Many<br />

commands accept an optional preceding count which is entered in decimal as<br />

Meta-digits, or as Ctrl-, which multiplies the current count (initially 1) by 4.<br />
