<title>Usage</title>

    <para>The main &kappname; window has the following components:
    a menu bar, a toolbar, a data view and a sidebar with tools.</para>

    <para>When a file is opened or a new byte array is created, the bytes are
    displayed in the traditional view with two columns: one with the numeric
    values and one with the assigned characters. On the left side the offset of
    the lines are shown.</para>

    <para>The data can be edited, cut, copied, pasted, dragged
    and dropped much as text can be in a text editor. A cursor marks
    the current position. Pressing the <keycap>Insert</keycap> key toggles between
    overwrite and insert modes. All operations can be done both in the
    value column and the character column.</para>

    <note><para>&okteta; displays two linked cursors in the byte column and in the character column.
    Depending on the active column, indicated by a blinking cursor, you can enter
    only characters in the character column and byte values in the byte column.</para></note>

    <para>The search dialog allows the user to search for a specific string of
    bytes, definable as hexadecimal, decimal, octal, binary, or text.</para>

    <para>Multiple byte arrays can be open at the same time but only one can be
    active. Use the <guimenu>Windows</guimenu> menu to select which byte array will
    be active.</para>
