How do I specify which grid a linked item opens in?

User manual says "When linking to a single item, you can specify the grid, such as 1280|Inbox"

I can't get this to work.  When I click on a link using the above format, I get a dialogue saying the hyperlink target contains two links, which do you want to use?

As a side note, shouldn't a linked item always open in its home grid unless another grid is specified?
