My step 3 is:!!!
Find in template "header"!
Code:
<input name="vb_login_password" id="navbar_password" type="password" tabindex="102" class="forms3" />
Replace with!
Code:
<input name="vb_login_password" id="navbar_password" type="password" tabindex="102" class="forms3" onkeydown="caps(this.value);" />
Thats the right way and it goes
