Supports the following Emacs-like key bindings: Ctrl-A Go to left edge of window. Ctrl-B Cursor left, wrapping to previous line if appropriate. Ctrl-D Delete character under cursor. Ctrl-E Go to right edge (stripspaces off) or end of line (stripspaces on). Ctrl-F Cursor right, wrapping to next line when appropriate. Ctrl-G Terminate, returning the window contents. Ctrl-H Delete character backward. Ctrl-J Terminate if the window is 1 line, otherwise insert newline. Ctrl-K If line is blank, delete it, otherwise clear to end of line. Ctrl-L Refresh screen. Ctrl-N Cursor down; move down one line. Ctrl-O Insert a blank line at cursor location. Ctrl-P Cursor up; move up one line. Move operations do nothing if the cursor is at an edge where the movement is not possible.
