+
+  <paragraph*|Keyboard modifiers>
+
+  <TeXmacs> makes use of the following keyboard modifiers:
+
+  <\description>
+    <item*|<prefix|S->>For shift key combinations.
+
+    <item*|<prefix|C->>For control key combinations.
+
+    <item*|<prefix|A->>For alternate key combinations.
+
+    <item*|<prefix|M->>For meta key combinations.
+  </description>
+
+  For instance, <key*|M-S-x> stands for the action which consists of
+  simultaneously pressing the three keys <prefix|M->, <prefix|S-> and
+  <key|x>.
+
+  The actual keyboard modifier keys depend on your system as indicated in the
+  following table

+
+  <paragraph*|Keyboard shortcuts>
+
+  Keyboard shortcuts are obtained by pressing several keys or \Pmodified
+  keys\Q in succession. For instance, the shortcut <key|- \<gtr\>>
+  corresponds on first pressing the <key|-> key and then the key
+  <key|\<gtr\>>. Inside mathematical formulas, this shortcut inserts the
+  arrow <math|<op|\<rightarrow\>>>. Similarly, the shortcut <key*|C-x C-f>
+  consists of first pressing the keys <prefix|C-> and <key|x> together, and
+  next pressing the keys <prefix|C-> and <key|f> again together. In the
+  <name|Emacs> \Plook and feel\Q, this shortcut enables you to open a new
+  file.
+
+  Some common keyboard prefixes are detailed in the section on <hlink|general
+  keyboard rules|../text/keyboard/man-general-rules.en.tm>. In cases when
+  <TeXmacs> keyboard shortcuts are superseded by shortcuts from the operating
+  system, <hlink|equivalents for the keyboard
+  modifiers|../config/man-config-keyboard.en.tm#kbd-escape-table> can be
+  obtained using the <key*|escape> key. For instance, <key*|escape> is
+  equivalent to <key|escape> and <key*|escape escape> is equivalent to
+  <key|escape escape>.
+
+  Notice that the <TeXmacs> menus and keyboard behavior are <em|contextual>,
+  <abbr|i.e.> they depend on the current mode (i.e. text mode or \Pmath
+  mode\Q), the current language and the position of the cursor inside your
+  document. For instance, inside math mode, you have special keyboard
+  shortcuts which are handy for typing mathematical formulas, but which are
+  useless in text mode.
+
+  <paragraph*|Special keys>
+
+  On some platforms, some special keys such as the Return key are depicted by
+  short glyphs. Below follows the table with all such special keys and there
+  meaning.
