Hello Mayra,
as the KB article mentions, this was only a feature for the Windows Client (prior to Version 6.7). The current DocuWare WebClient does not support this feature. (However, I already had several customers ask for this)
Maybe there is already an idea over at
Uservoice.com - if not, you could create one.
Hope this helps.
