Lastly, there are a small number of commands which require typed
input on the command line. The command line is
reached by hitting ESC. This places the cursor at the beginning of the
command line which is on the last row and ordinarily displays some status
information. After ESC however text can be input here for the following
functions:
Command Line Operations (requires
text input so terminate line with a
return)
esc goto or leave command line

+number down n lines
-number up n lines

@number start at column n
@+number scroll left n columns
