		107	=item $string
		108
		109	A perl text string, with an emphasis on I<text>. It can store all unicode
		110	characters and is to be distinguished with text encoded in a specific
		111	encoding (often locale-specific) and binary data.

126		171
		172	=item on_sel_extend $term
		173
		174	Called whenever the user tries to extend the selection (e.g. with a double
		175	click) and is either supposed to return false (normal operation), or
		176	should extend the selection itelf and return true to suppress the built-in
		177	processing.

		210
		211	=item on_osc_seq $term, $string
		212
		213	Called whenever the B<ESC ] 777 ; string ST> command sequence (OSC =
		214	operating system command) is processed. Cursor position and other state
		215	information is up-to-date when this happens. For interoperability, the
		216	string should start with the extension name and a colon, to distinguish
		217	it from commands for other extensions, and this might be enforced in the
		218	future.
		219
		220	Be careful not ever to trust (in a security sense) the data you receive,
		221	as its source can not easily be controleld (e-mail content, messages from
		222	other users on the same system etc.).
		223
		224	=item on_add_lines $term, $string
		225
		226	Called whenever text is about to be output, with the text as argument. You
		227	can filter/change and output the text yourself by returning a true value
		228	and calling C<< $term->scr_add_lines >> yourself. Please note that this
		229	might be very slow, however, as your hook is called for B<all> text being
		230	output.
		231
		232	=item on_line_update $term, $row
		233
		234	Called whenever a line was updated or changed. Can be used to filter
		235	screen output (e.g. underline urls or other useless stuff). Only lines
		236	that are being shown will be filtered, and, due to performance reasons,
		237	not always immediately.
		238
		239	The row number is always the topmost row of the line if the line spans
		240	multiple rows.
		241
		242	Please note that, if you change the line, then the hook might get called
		243	later with the already-modified line (e.g. if unrelated parts change), so
		244	you cannot just toggle rendition bits, but only set them.
