External link in wordpress

[kdjuiopo]

Using the visual editor with wordpress, I have some problems about the external links :

I am not able to add the nofollow in link.
how can I do ?

I am not able to choose the size of new window ( width and height ). AFter the click, I wish to have one new window with width = xxx and height xxx.
how can I do ?

could I use one other visual editor ? if yes how ?
