104always represents one screen cell. See L<row_t> for a discussion of this format.
105
106=item $string
107
108A perl text string, with an emphasis on I<text>. It can store all unicode
109characters and is to be distinguished with text encoded in a specific

213Be careful not ever to trust (in a security sense) the data you receive,
214as its source can not easily be controleld (e-mail content, messages from
215other users on the same system etc.).
216
217=item on_add_lines $term, $string
218
219Called whenever text is about to be output, with the text as argument. You
220can filter/change and output the text yourself by returning a true value
221and calling C<< $term->scr_add_lines >> yourself. Please note that this
222might be very slow, however, as your hook is called for B<all> text being
223output.
224
225=item on_line_update $term, $row
226
227Called whenever a line was updated or changed. Can be used to filter
228screen output (e.g. underline urls or other useless stuff). Only lines
229that are being shown will be filtered, and, due to performance reasons,
230not always immediately.
231
232The row number is always the topmost row of the line if the line spans
233multiple rows.
234
235Please note that, if you change the line, then the hook might get called
236later with the already-modified line (e.g. if unrelated parts change), so
237you cannot just toggle rendition bits, but only set them.

259does focus in processing.

263Called wheneever the window loses keyboard focus, before rxvt-unicode does

280Called whenever the corresponding X event is received for the terminal If
281the hook returns true, then the even will be ignored by rxvt-unicode.
282
283The event is a hash with most values as named by Xlib (see the XEvent
284manpage), with the additional members C<row> and C<col>, which are the row
285and column under the mouse cursor.
