Tab size of Toolbar 'text'

Can I manipulate, or set a default-width for the tabulator-width of the standard Toolbar ‘text’,
witch I use to edit a html type field ?

(Hope this question is understandable verbalised, please let me know if not…)

I feared the question was not clear:

I like to give my User a simple opportunity to format a bit of text in a html field, so that
it looks nice formatted for printing comment in a memofield.

With the standard Toolbar ‘text’ I have something like this:[attachment=1]Prtscrn_01.jpg[/attachment]

This allows also tabulator (marked with red arrow)

Question 1: Can I influence the width of the tabulator
Question 2: The tabulator disappears after leaving the field (see next picture). How can I keep it ?
Question 3: Are I’m on the right way with this approach (using standard Toolbar ‘text’ and htmlfield for Users to format and print)

Thank you for any suggestions
