213A support package that tries to make editing with readline easier. At the
214moment, it reacts to clicking with the left mouse button by trying to
215move the text cursor to this position. It does so by generating as many
216cursor-left or cursor-right keypresses as required (the this only works
217for programs that correctly support wide characters).

311This (experimental) perl extension implements OnTheSpot editing. It does
312not work perfectly, and some input methods don't seem to work well with
313OnTheSpot editing in general, but it seems to work at leats for SCIM and
314kinput2.
