<h2>C1 (8-Bit) Control Characters</h2>
<p style="margin-top: 1em" valign="top">The <i>xterm</i>
program recognizes both 8-bit and 7-bit control characters.
It generates 7-bit controls (by default) or 8-bit if S8C1T
is enabled. The following pairs of 7-bit and 8-bit control
characters are equivalent:</p>

<h2>VT100 Mode</h2>
<p style="margin-top: 1em" valign="top">Most of these
control sequences are standard VT102 control sequences, but
there is support for later DEC VT terminals (i.e., VT220,
VT320, VT420, VT510), as well as ISO 6429 and <i>aixterm</i>
color controls. The only VT102 feature not supported is
auto-repeat, since the only way X provides for this will
affect all windows. There are additional control sequences
to provide <i>xterm-</i>dependent functions, such as the
scrollbar or window size. Where the function is specified by
DEC or ISO 6429, the code assigned to it is given in
parentheses. The escape codes to designate and invoke
character sets are specified by ISO 2022; see that document
for a discussion of character sets.</p>

<h2>Alt and Meta Keys</h2>
<p style="margin-top: 1em" valign="top">Many keyboards have
keys labeled &quot;Alt&quot;. Few have keys labeled
&quot;Meta&quot;. However, <i>xterm</i>&rsquo;s default
translations use the <i>Meta</i> modifier. Common keyboard
configurations assign the <i>Meta</i> modifier to an
&quot;Alt&quot; key. By using <i>xmodmap</i> one may have
the modifier assigned to a different key, and have
&quot;real&quot; alt and meta keys. Here is an example:</p>
<p style="margin-left:22%; margin-top: 1em">! put meta on
mod3 to distinguish it from alt <br>
keycode 64 = Alt_L <br>
clear mod1 <br>
add mod1 = Alt_L <br>
keycode 115 = Meta_L <br>
clear mod3 <br>
add mod3 = Meta_L</p>
<p style="margin-top: 1em" valign="top">The
<b>metaSendsEscape</b> resource (and <b>altSendsEscape</b>
if <b>altIsNotMeta</b> is set) can be used to control the
way the <i>Meta</i> modifier applies to ordinary keys unless
the <b>modifyOtherKeys</b> resource is set:</p>
<p style="margin-left:17%;">- prefix a key with the
<small><small>ESC</small></small> character. <br>
- shift the key from codes 0-127 to 128-255 by adding
128.</p>
<p style="margin-top: 1em" valign="top">The table shows the
result for a given character &quot;x&quot; with modifiers
according to the default translations with the resources set
on or off. This assumes <b>altIsNotMeta</b> is set:</p>

<a name="PC-Style Function Keys"></a>
<h2>PC-Style Function Keys</h2>
<p style="margin-top: 1em" valign="top">If <i>xterm</i>
does minimal translation of the function keys, it usually
does this with a PC-style keyboard, so PC-style function
keys result. Sun keyboards are similar to PC keyboards. Both
have cursor and scrolling operations printed on the keypad,
which duplicate the smaller cursor and scrolling
keypads.</p>
<p style="margin-top: 1em" valign="top">X does not
predefine NumLock (used for VT220 keyboards) or Alt (used as

keys are recognized as modifiers when enabled by the

<p valign="top">The home- and end-keys (unlike PageUp and
other keys also on the 6-key editing keypad) are considered
&quot;cursor keys&quot; by <i>xterm</i>. Their mode is also
controlled by the <b>DECCKM</b> escape sequence:</p>
<p align=center style="margin-top: 1em" valign="top"><img src="grohtml-285553.png" alt="Image grohtml-285553.png"></p>
<p style="margin-top: 1em" valign="top">The application

the mode specified via the <b>DECPNM</b> and <b>DECPAM</b>
escape sequences. Use the NumLock key to override the

<p style="margin-top: 1em" valign="top">Not all keys are
present on the Sun/PC keypad (e.g., PF1, Tab), but are
supported by the program.</p>
<p align=center style="margin-top: 1em" valign="top"><img src="grohtml-285554.png" alt="Image grohtml-285554.png"></p>

<p align=center style="margin-top: 1em" valign="top"><img src="grohtml-285555.png" alt="Image grohtml-285555.png"></p>
<p style="margin-top: 1em" valign="top">Older versions of
<i>xterm</i> implement different escape sequences for F1
through F4. These can be activated by setting the
<b>oldXtermFKeys</b> resource. However, since they do not
correspond to any hardware terminal, they have been
deprecated. (The DEC VT220 reserves F1 through F5 for local
functions such as <b>Setup</b>).</p>
<p align=center style="margin-top: 1em" valign="top"><img src="grohtml-285556.png" alt="Image grohtml-285556.png"></p>
<p valign="top">In normal mode, i.e., a Sun/PC keyboard
when the <b>sunKeyboard</b> resource is false, <i>xterm</i>
recognizes function key modifiers which are parameters
appended before the final character of the control
sequence.</p>
<p align=center style="margin-top: 1em" valign="top"><img src="grohtml-285557.png" alt="Image grohtml-285557.png"></p>
<p valign="top">For example, shift-F5 would be sent as
<small><small>CSI</small></small> 1 5 ; 2 ~</p>
<p style="margin-top: 1em" valign="top">If the
<b>alwaysUseMods</b> resource is set, the Meta modifier also
is recognized, making parameters 9 through 16.</p>
<a name="VT220-Style Function Keys"></a>
<h2>VT220-Style Function Keys</h2>
<p style="margin-top: 1em" valign="top">However,
<i>xterm</i> is most useful as a DEC VT102 or VT220
emulator. Set the <b>sunKeyboard</b> resource to true to
force a Sun/PC keyboard to act like a VT220 keyboard.</p>
<p style="margin-top: 1em" valign="top">The VT102/VT220

<a name="VT52-Style Function Keys"></a>
<h2>VT52-Style Function Keys</h2>
<p style="margin-top: 1em" valign="top">A VT52 does not
have function keys, but it does have a numeric keypad and
cursor keys. They differ from the other emulations by the
prefix. Also, the cursor keys do not change:</p>
<p align=center style="margin-top: 1em" valign="top"><img src="grohtml-2855511.png" alt="Image grohtml-2855511.png"></p>
<p valign="top">The keypad is similar:</p>

<a name="Sun-Style Function Keys"></a>
<h2>Sun-Style Function Keys</h2>
<p style="margin-top: 1em" valign="top">The <i>xterm</i>
program provides support for Sun keyboards more directly, by
a menu toggle that causes it to send Sun-style function key
codes rather than VT220. Note, however, that the <i>sun</i>
and <i>VT100</i> emulations are not really compatible. For
example, their wrap-margin behavior differs.</p>
<p style="margin-top: 1em" valign="top">Only function keys
are altered; keypad and cursor keys are the same. The
emulation responds identically. See the xterm-sun terminfo
entry for details.</p>
<a name="HP-Style Function Keys"></a>
<h2>HP-Style Function Keys</h2>
<p style="margin-top: 1em" valign="top">Similarly,
<i>xterm</i> can be compiled to support HP keyboards. See
the xterm-hp terminfo entry for details.</p>
<a name="The Alternate Screen Buffer"></a>
<h2>The Alternate Screen Buffer</h2>
<p style="margin-top: 1em" valign="top"><i>Xterm</i>
maintains two screen buffers. The normal screen buffer
allows you to scroll back to view saved lines of output up
to the maximum set by the <b>saveLines</b> resource. The
alternate screen buffer is exactly as large as the display,
contains no additional saved lines. When the alternate
screen buffer is active, you cannot scroll back to view
saved lines. <i>Xterm</i> provides control sequences and
menu entries for switching between the two.</p>
<p style="margin-top: 1em" valign="top">Most full-screen
applications use terminfo or termcap to obtain strings used
to start/stop full-screen mode, i.e., <i>smcup</i> and
<i>rmcup</i> for terminfo, or the corresponding <i>ti</i>
and <i>te</i> for termcap. The <b>titeInhibit</b> resource
removes the <i>ti</i> and <i>te</i> strings from the TERMCAP
string which is set in the environment for some platforms.
That is not done when <i>xterm</i> is built with terminfo
libraries because terminfo does not provide the whole text
of the termcap data in one piece. It would not work for
terminfo anyway, since terminfo data is not passed in
environment variables; setting an environment variable in
this manner would have no effect on the application&rsquo;s
ability to switch between normal and alternate screen
buffers. Instead, the newer private mode controls (such as 1
0 4 9 ) for switching between normal and alternate screen
buffers simply disable the switching. They add other
features such as clearing the display for the same reason:
to make the details of switching independent of the
application that requests the switch.</p>
<a name="Bracketed Paste Mode"></a>
<h2>Bracketed Paste Mode</h2>
<p style="margin-top: 1em" valign="top">When bracketed
paste mode is set, pasted text is bracketed with control
sequences so that the program can differentiate pasted text
from typed-in text. When bracketed paste mode is set, the
program will receive: <small><small><br>
ESC</small></small> [ 200 ~, <br>
followed by the pasted text, followed by <small><small><br>
ESC</small></small> [ 201 ~.</p>
<a name="Title Modes"></a>
<h2>Title Modes</h2>
<p style="margin-top: 1em" valign="top">The window- and
icon-labels can be set or queried using control sequences.
As a VT220-emulator, <i>xterm</i> &quot;should&quot; limit
the character encoding for the corresponding strings to
ISO-8859-1. Indeed, it used to be the case (and was
documented) that window titles had to be ISO-8859-1. This is
no longer the case. However, there are many applications
which still assume that titles are set using ISO-8859-1. So
that is the default behavior.</p>
<p style="margin-top: 1em" valign="top">If <i>xterm</i> is
running with UTF-8 encoding, it is possible to use window-
and icon-labels encoded using UTF-8. That is because the
underlying X libraries (and many, but not all) window
managers support this feature.</p>
<p style="margin-top: 1em" valign="top">The
<b>utf8Title</b> X resource setting tells <i>xterm</i> to
disable a reconversion of the title string back to
ISO-8859-1, allowing the title strings to be interpreted as
UTF-8. The same feature can be enabled using the title mode
control sequence described in this summary.</p>
<p style="margin-top: 1em" valign="top">Separate from the
ability to set the titles, <i>xterm</i> provides the ability
to query the titles, returning them either in ISO-8859-1 or
UTF-8. This choice is available only while <i>xterm</i> is
using UTF-8 encoding.</p>
<p style="margin-top: 1em" valign="top">Finally, the
characters sent to, or returned by a title control are less
constrained than the rest of the control sequences. To make
them more manageable (and constrained), for use in shell
scripts, <i>xterm</i> has an optional feature which decodes
the string from hexadecimal (for setting titles) or for
encoding the title into hexadecimal when querying the
value.</p>
<a name="Mouse Tracking"></a>
<h2>Mouse Tracking</h2>
<p style="margin-top: 1em" valign="top">The VT widget can
be set to send the mouse position and other information on
button presses. These modes are typically used by editors
and other full-screen applications that want to make use of
the mouse.</p>

mouse protocol limits the <i>C <small>x</small></i> and <i>C

<table width="100%" border=0 rules="none" frame="void"

<td width="20%">

<p style="margin-left:17%;">This enables UTF-8 encoding for
<i>C <small>x</small></i> and <i>C <small>y</small></i>
under all tracking modes, expanding the maximum encodable
position from 223 to 2015. For positions less than 95, the
resulting output is identical under both modes. Under
extended mouse mode, positions greater than 95 generate
&quot;extra&quot; bytes which will confuse applications
which do not treat their input as a UTF-8 stream. Likewise,
<i>C <small>b</small></i> will be UTF-8 encoded, to reduce
confusion with wheel mouse events. <br>
Under normal mouse mode, positions outside (160,94) result
in byte pairs which can be interpreted as a single UTF-8
character; applications which do treat their input as UTF-8
will almost certainly be confused unless extended mouse mode
is active. <br>
This scheme has the drawback that the encoded coordinates
will not pass through <i>luit</i> unchanged, e.g., for
locales using non-UTF-8 encoding.</p>
