  <title>Keyboard shortcuts in the editor</title>

  <para>This short text describes key behavior in the editor pane. The term
  "Move to inside segment" means, that the cursor moves to the beginning of
  the segment if it was previously before the segment, and to the end of the
  segment if it was previously after it.</para>

  <para>* These keys behave differently when the cursor is outside the
  editable segment:</para>

  <itemizedlist>
    <listitem>
      <para><emphasis role="bold">Home: </emphasis> cursor to the beginning of
      the active segment</para>
    </listitem>

    <listitem>
      <para><emphasis role="bold">End: </emphasis> cursor to the end of the
      active segment</para>
    </listitem>

    <listitem>
      <para><emphasis role="bold">Backspace: </emphasis>nothing</para>
    </listitem>

    <listitem>
      <para><emphasis role="bold">Delete: </emphasis>nothing</para>
    </listitem>

    <listitem>
      <para><emphasis role="bold">Any char key,</emphasis> if clicked outside
      editable segment, will be ignored.</para>
    </listitem>
  </itemizedlist>

  <para>The "Shift" key doesn't exhibit any special behavior per se: when the
  "Shift" key is pressed, all keys move the cursor in their usual manner,
  except in the case of the <literal>Shift+Enter</literal> combination, that
  inserts a line break into the text.</para>

  <para>System-wide commands Select All (<keycap>Ctrl+A</keycap>), Paste
  (<emphasis role="bold">Ctrl+V</emphasis>), Cut (<emphasis
  role="bold">Ctrl+X</emphasis>), copy (<emphasis
  role="bold">Ctrl+C)</emphasis>, Insert match <emphasis
  role="bold">(Ctrl+I</emphasis>) and Insert source (<emphasis
  role="bold">Ctrl+Shift+I</emphasis>) act in principle on the text within the
  currently open segment only.</para>
  
  <para>It is possible to move from one pane to another (for instance, from the
  Editor to the Fuzzy Matches pane) using <keycap>Ctrl+Tab</keycap>.
  <keycap>Ctrl+Shift+Tab</keycap> moves back to the previous pane. The
  shortcuts <keycap>Ctrl+A</keycap> and <keycap>Ctrl+C</keycap> work
  in panes, allowing to copy all or some of the information to the clipboard.</para>

  <para>Note that you can reassign the shortcuts to your own preferences. See

  Customization</link></para>
