Código ver en pantalla completa :.

Código:

<form>
<input TYPE="BUTTON" NAME="BTN_FullScreen" VALUE="Modo pantalla completa"
OnClick="window.open(document.location, 'big', 'fullscreen=yes')">
</form> 

Agrego minizar pantalla ( lo contrario ) :

Código:


<!---INÍCIO--->
<input type="button" value="Minimizar ventana" onclick_fckprotectedatt=" onclick="window.moveBy(5000,5000); min = 'si';"" style="font-family:Verdana"><script>min = "no"; function volver(){if(min == "si"{window.moveTo(0,0); min = "no"}}; window.onfocus = volver
</script> <style> .animado {position:absolute;visibility:visible;top:-50px;font-size:10pt;font-family:Arial;font-weight:bold;color:Blak;} </style>
<!---FIN--->
