Expands or collapses the current line while outlining is displayed.
While outlining is displayed, if the current line is collapsed, this command expands the current line, and if the current line is expanded, this command collapses the current line. It is the same effect as clicking the "+" button or the "-" button at the left side of a text line. A plug-in for outlining is necessary to display the outlining.
