  63.     The <span class="guimenuitem">Float</span> command converts a normal selection
  64.     into a ‚Äú<span class="quote">floating selection</span>‚Äù. You can find more information
  65.     about
  66.     <a class="link" href="glossary.html#glossary-floatingselection" title="Floating Selection">floating selections</a>
  67.     in the Glossary.

  69.       <p>
  70.     In early versions of <acronym class="acronym">GIMP</acronym>, floating
  71.     selections were used for performing operations on a limited part of an
  72.     image. You can do that more easily now with layers, but you can still
  73.     use this way of working with images. In addition to using the
  74.     <span class="guimenuitem">Float</span> command, you can also create a floating
  75.     selection by moving a selection using the ‚Äú<span class="quote">Move</span>‚Äù tool,
  76.     without pressing the <span class="keycap"><strong>Alt</strong></span> key (or
  77.     <span class="keycap"><strong>Shift</strong></span>+<span class="keycap"><strong>Alt</strong></span> in
  78.     Linux), which automatically creates a floating selection. You can also
  79.     create a temporary layer, named ‚Äú<span class="quote">Floating Selection</span>‚Äù, with
  80.     the entries on the <a class="link" href="gimp-layer-menu.html#gimp-layer-introduction" title="10.1.¬† Introduction to the ‚ÄúLayer‚Äù Menu">Layer</a>
  81.     menu.
  82.   </p>
  83.       <p>
  84.     You cannot perform any operations on other layers if the image has a
  85.     floating selection, so after you make the changes you want to the
  86.     floating selection, you have to <span class="emphasis"><em>anchor</em></span> it. That is,
  87.     you have to attach it to a normal (non-floating) layer, usually the
  88.     original layer (the one which was active previously). To anchor the
  89.     floating selection, use the
  90.     <a class="link" href="gimp-layer-anchor.html" title="10.4.¬† Anchor layer">Anchor Layer</a> command. You can
  91.     also anchor it to an existing layer by clicking anywhere on the image
  92.     outside of the floating selection, which then merges it with the
  93.     background layer. You can also anchor it to a new layer by using the
  94.     <a class="link" href="gimp-layer-new.html" title="10.2.¬† New Layer">New Layer</a> command.

  109.       command, you may have difficulty selecting a precise area of the
  110.       image which you want in a layer. To avoid this problem, you can make a
  111.       rectangular selection, transform it into a floating selection and
  112.       anchor it to a new layer. Then simply remove the original layer.
