a -- Append command default range syntax . a "a" is for appending new lines of text after a given line. If no line number is typed before the "a", text will be appended after the current line. The last line appended becomes the current line. To signal the end of the appended text, you type a "." on a line by itself. Control characters "f", "v", "l", and "k" work differently for "a" command than for "v". "a:" works as a one line append (i.e. anything following the colon is appended after the current line). To return to the command directory, type "hcomdir." See also: "hcc" (control characters) and "hc" (change).
