Hi,
Tab order can be controled with tabindex property on some html tags. Look thi example:
<html>
<head>
<title>TAB Order test</title>
</head>
<body>
<form>
Text1 (first tab):
<input type="text" name="txt1" tabindex=1 /><br />
Text2 (third tab):
<input type="text" name="txt2" tabindex=3 /><br />
Text3 (fourth tab):
<input type="text" name="txt3" tabindex=4 /><br />
Text4 (second tab):
<input type="text" name="txt4" tabindex=2 /><br />
</form>
</body>
</html></html>
Suported tags are a, textarea, select and input types...
If you want to skip control then set its tabindex to 0 (tabindex=0).
One more link that can be useful. Look
control your tab order and cursor focus [
