<div name="quoted-content">
<div style="font-family: Verdana;font-size: 12.0px;">
<div>In math mode, material in an hbox is formatted in horizontal mode.
I don't see the necessity of assigning to \textfont1. If you just want
to use these characters once in a while, you can pick a size and use
hboxes. You could define a family, but I don't think it's meant to work
that way. You want to use individual characters from this font with
the normal family. Since you can put the hboxes into macro definitions,
I think this solution would be adequate. If you're only using a few
bold Greek letters, it doesn't seem like it would be worth it to me to
define \textfont, \scriptfont and \scriptscriptfont. However, it would
certainly be possible. I'm not sure how switching families in the
middle of an equation would work, since I've never tried to do this. I
think it would inadvisable.</div>

<div style="font-family: Lucida Sans;font-size: 12.0px;">
<div style="font-size: 12.0px;font-family: Lucida Sans;">Thanks.<br>
Yes it suffices, but I also need these boldface letters in subscripts.<br>
I am puzzled by the necessity of using \hbox. Can't one design a setting
working like \bf or \it ?<br>
