idlok(bf)[permalink][rdoc][TODO]
If +bool+ is +true+ curses considers using the hardware insert/delete line feature of terminals so equipped.
If +bool+ is +false+, disables use of line insertion and deletion. This option should be enabled only if the application needs insert/delete line, for example, for a screen editor.
It is disabled by default because insert/delete line tends to be visually annoying when used in applications where it is not really needed. If insert/delete line cannot be used, curses redraws the changed portions of all lines.
