you need the same for TSynPluginTemplateEdit (template edit, which 
includes it's own syncro mode)

    TSynPluginTemplateEdit.Create(FEditor);
    FSyncroEdit := TSynPluginSyncroEdit.Create(FEditor);

Yes, the question is, if it is ok for codetools, since it would be 
called before the paste => that is you have to interpret the 
to-be-pasted text before it is part of the source

At the moment you can indent based on the complete source *after*  the paste

The alternative is a combination:
- in the OnPaste event you store the text to be pasted (as well as the 
mode normal, column ....)
- in the OnIndent, you take the final caret pos and you know how far to 
go back (since the pasted text always ends at the final caret pos)


I'll update you, when I got it done.
