I'm wondering what the best practice is when using Xerte to link to external webpages. I understand that it's best to open them in the same window to avoid confusion for screen reader users. But in Xerte that means they open in a window with no 'back' button. Practically, they need to be opened in a new window. So do we have to put that in the link text? Or is there another way of telling a screen reader user that the link will open a new window? Thanks.
