Hi again,
I am using Texmacs version 1.99.2.
I remarked that when I change the alignment of a document (Menu "Document", "Paragraph...", "Basic" tab), the document is logically marked as modified (an asterisk appears in the title bar). Meanwhile, it is not possible to undo the operation: when, just after that, I type "ctrl+z" or click on the menu "Edit->Undo", it undoes the edits before the change of alignment but not the alignment.
Is this supposed to work like that? Is there an undo operation for the alignment (besides manually putting back the alignment) ?
