Currently I have 5 workbook links and a help page link on each of my workbooks (enabled through url dashboard actions). For the workbook links, I have it so that the new workbooks open in the same tab (i.e. ?:linktarget=_self&:embed=yes) when selected. This will allow me to click on a workbook link and go to that workbook without it popping up in a new tab. However it concatenates that string to the end of the url making future links also open in the same tab. This would be fine if I'm jumping around from workbook to workbook, but I do have a help page link in each workbook that I want opened in a new tab when clicked, not the same tab.
