Perhaps <INPUT TYPE="submit" VALUE="Submit" DEFAULT> would be more
appropriate since it is more in line with the current style for
other form controls, e.g. <INPUT TYPE="radio" VALUE="Submit" CHECKED>
While we're at it, how about a modification which would allow the
text displaed on the button to be different from the value, e.g.
<INPUT TYPE="submit" VALUE="RunQuery MyQuery" VALUE="Ok">
It would also seem to be a simple matter to add the "&" Control Key
specification technique ala MS Windows, e.g. "&Ok" results in
an underlined "O" in the Ok displayed and sets Ctrl-O to simulate
clicking the button.
