+- selection (enabled by default)
+
+-
+(More) intelligent selection. This extension tries to be more intelligent
+when the user extends selections (double-click). Right now, it tries to
+select urls and complete shell-quoted arguments, which is very convenient,
+too, if your ls supports
--quoting-style=shell.

It also offers the following bindable keyboard command:

+- option-popup (enabled by default)
+
+-
+Binds a popup menu to Ctrl-Button2 that lets you toggle (some) options at
+runtime.
+
+
+- selection-popup (enabled by default)
+
+-
+Binds a popup menu to Ctrl-Button3 that lets you convert the selection
+text into various other formats/action (such as uri unescaping, perl
+evalution, web-browser starting etc.), depending on content.
+
+
+- searchable-scrollback<hotkey> (enabled by default)
+
+-
+Adds regex search functionality to the scrollback buffer, triggered
+by a hotkey (default:
M-s). When in search mode, normal terminal
+input/output is suspended.
+
+-
+
/ starts an incremental regex search, n searches further, p or
+N jump to the previous match, G jumps to the bottom and clears the
+history, enter leaves search mode at the current position and escape
+returns to the original position.
+
+
+- digital-clock
+
+-
+Displays a digital clock using the built-in overlay.
+
+
+- mark-urls
+
+-
+Uses per-line display filtering (
on_line_update) to underline urls.
+
+
+- block-graphics-to-ascii
+
+-
+A not very useful example of filtering all text output to the terminal,
+by replacing all line-drawing characters (U+2500 .. U+259F) by a
+similar-looking ascii character.
+
+
+- example-refresh-hooks
+
+-
+Displays a very simple digital clock in the upper right corner of the
+window. Illustrates overwriting the refresh callbacks to create your own
+overlays or changes.

All objects (such as terminals, time watchers etc.) are typical
reference-to-hash objects. The hash can be used to store anything you
like. All members starting with an underscore (such as _ptr or
-_hook) are reserved for internal uses and must not be accessed or
+_hook) are reserved for internal uses and MUST NOT be accessed or
modified).
When objects are destroyed on the C++ side, the perl object hashes are
emptied, so its best to store related objects such as time watchers and
the like inside the terminal object so they get destroyed as soon as the
terminal is destroyed.
+Argument names also often indicate the type of a parameter. Here are some
+hints on what they mean:
+
+- $text
+
+-
+Rxvt-unicodes special way of encoding text, where one ``unicode'' character
+always represents one screen cell. See ROW_t for a discussion of this format.
+
+
+- $string
+
+-
+A perl text string, with an emphasis on text. It can store all unicode
+characters and is to be distinguished with text encoded in a specific
+encoding (often locale-specific) and binary data.
+
+
+- $octets
+
+-
+Either binary data or - more common - a text string encoded in a
+locale-specific way.
+
+
+
+
+
+Very perl extension is a perl class. A separate perl object is created
+for each terminal and each extension and passed as the first parameter to
+hooks. So extensions can use their $self object without having to think
+about other extensions, with the exception of methods and members that
+begin with an underscore character _: these are reserved for internal
+use.
+Although it isn't a urxvt::term object, you can call all methods of the
+urxvt::term class on this object.
+It has the following methods and data members:
+
+- $urxvt_term = $self->{term}

+Returns the
urxvt::term object associated with this instance of the
+extension. This member must not be changed in any way.

+- $self->enable ($hook_name => $cb, [$hook_name => $cb..])

+Dynamically enable the given hooks (named without the
on_ prefix) for
+this extension, replacing any previous hook. This is useful when you want
+to overwrite time-critical hooks only temporarily.

+
+
+- $term->want_refresh
+
+-
+Requests a screen refresh. At the next opportunity, rxvt-unicode will

+
Used after changing terminal contents to display them.
+
+
+- $text = $term->ROW_t ($row_number[, $new_text[, $start_col]])
+
+-
+Returns the text of the entire row with number
$row_number. Row 0
+is the topmost terminal line, row $term->$ncol-1 is the bottommost
+terminal line. The scrollback buffer starts at line -1 and extends to
+line -$term->nsaved. Nothing will be returned if a nonexistent line
+is requested.
+
+-
+
If $new_text is specified, it will replace characters in the current
+line, starting at column $start_col (default 0), which is useful
+to replace only parts of a line. The font index in the rendition will
+automatically be updated.
+
+-
+
$text is in a special encoding: tabs and wide characters that use more
+than one cell when displayed are padded with urxvt::NOCHAR characters
+(chr 65535). Characters with combining characters and other characters
+that do not fit into the normal tetx encoding will be replaced with
+characters in the private use area.
+
+-
+
You have to obey this encoding when changing text. The advantage is
+that substr and similar functions work on screen cells and not on
+characters.
+
+-
+
The methods $term->special_encode and $term->special_decode
+can be used to convert normal strings into this encoding and vice versa.
+
+
+- $rend = $term->ROW_r ($row_number[, $new_rend[, $start_col]])
+
+-
+Like
$term->ROW_t, but returns an arrayref with rendition
+bitsets. Rendition bitsets contain information about colour, font, font
+styles and similar information. See also $term->ROW_t.
+
+-
+
When setting rendition, the font mask will be ignored.
+
+-
+
See the section on RENDITION, above.
+
+
+- $length = $term->ROW_l ($row_number[, $new_length])
+
+-
+Returns the number of screen cells that are in use (``the line
+length''). Unlike the urxvt core, this returns
$term->ncol if the
+line is joined with the following one.
+
+
+- $bool = $term->is_longer ($row_number)
+
+-
+Returns true if the row is part of a multiple-row logical ``line'' (i.e.
+joined with the following row), which means all characters are in use
+and it is continued on the next row (and possibly a continuation of the
+previous row(s)).
+
+
+- $line = $term->line ($row_number)
+
+-
+Create and return a new
urxvt::line object that stores information
+about the logical line that row $row_number is part of. It supports the
+following methods:
+
+
+- $text = $line->t ([$new_text])
+
+-
+Returns or replaces the full text of the line, similar to
ROW_t
+
+
+- $rend = $line->r ([$new_rend])
+
+-
+Returns or replaces the full rendition array of the line, similar to
ROW_r
+
+
+- $length = $line->l
+
+-
+Returns the length of the line in cells, similar to
ROW_l.
+
+
+- $rownum = $line->beg
+
+- $rownum = $line->end
+
+-
+Return the row number of the first/last row of the line, respectively.
+
+
+- $offset = $line->offset_of ($row, $col)
+
+-
+Returns the character offset of the given row|col pair within the logical
+line.
+
+
+- ($row, $col) = $line->coord_of ($offset)
+
+-
+Translates a string offset into terminal coordinates again.
+
+
+- $text = $term->special_encode $string
+
+-
+Converts a perl string into the special encoding used by rxvt-unicode,
+where one character corresponds to one screen cell. See
+
$term->ROW_t for details.
+
+
+- $string = $term->special_decode $text
+
+-
+Converts rxvt-unicodes text reprsentation into a perl string. See
+
$term->ROW_t for details.
+
+
+- $success = $term->grab_button ($button, $modifiermask)
+
+-
+Registers a synchronous button grab. See the XGrabButton manpage.
+
+
+- $success = $term->grab ($eventtime[, $sync])
+
+-
+Calls XGrabPointer and XGrabKeyboard in asynchronous (default) or
+synchronous (
$sync is true). Also remembers the grab timestampe.
+
+
+- $term->allow_events_async
+
+-
+Calls XAllowEvents with AsyncBoth for the most recent grab.
+
+
+- $term->allow_events_sync
+
+-
+Calls XAllowEvents with SyncBoth for the most recent grab.
+
+
+- $term->allow_events_replay
+
+-
+Calls XAllowEvents with both ReplayPointer and ReplayKeyboard for the most
+recent grab.
+
+
+- $term->ungrab
+
+-
+Calls XUngrab for the most recent grab. Is called automatically on
+evaluation errors, as it is better to lose the grab in the error case as
+the session.
+
+
+
+
+
+
+- $popup->add_title ($title)
+
+-
+Adds a non-clickable title to the popup.
+
+
+- $popup->add_separator ([$sepchr])
+
+-
+Creates a separator, optionally using the character given as
$sepchr.
+
+
+- $popup->add_button ($text, $cb)
+
+-
+Adds a clickable button to the popup.
$cb is called whenever it is
+selected.
+
+
+- $popup->add_toggle ($text, $cb, $initial_value)
+
+-
+Adds a toggle/checkbox item to the popup. Teh callback gets called
+whenever it gets toggled, with a boolean indicating its value as its first
+argument.
+
+
+- $popup->show
+
+-
+Displays the popup (which is initially hidden).
