<form>
<textarea name="tsttxt" ONSELECT="markSelection(this);" ONCLICK="markSelection(this);" ONKEYUP="markSelection(this);"></textarea>
<input type="button" value="BOLD" onClick="insertTag('tsttxt', 'b', true)">
<input type="button" value="PARAGRAPH" onClick="insertTag('tsttxt', 'p', false)">
</form>
