Currently, there's no toolbar button to add pre tags around some text.
What is pre tags for you ? in message as html ?
Yes, <pre> tags in HTML mail.
Indeed we don't have it. But you can insert html if you want.
(In reply to Laurent Montel from comment #3) > Indeed we don't have it. > But you can insert html if you want. Yes, but a toolbar button would be easier. In particular, it would mean you can select some text and insert <pre> tags around it, which isn't possible with the Insert HTML feature.
it's possible now :) But yep I will look at how I can do it.
