tabIndex="-1" and IE 6

[jitseschaafsma]

I thought that tabindex=-1 prevents users from tabbing in to the field.

<input type="text" tabindex="-1" readOnly value="some value">


However, it appears that the user can stil go the the textfield beause it gets selected.
What is their that i do not understand about tabindex="-1"

Thanks Jitse
