I want to choose where they open by myself, thank you very much.
Maybe this is a little bit too simplistic, but by holding down the ctrl-key while clicking, you get the link opened in a new tab, by holding down the shift-key while clicking, you get the link opened in a new browserwindow (this is at least the case in firefox-browsers). For IE 6, holding down the ctrl-or shift-key opens the link in a new browserwindow.
Hope this helps,
Birger
