Link nodes are handy and when going between several tabs are really useful.
But when the link is on the one tab it can be problematic.
I am in the bottom right corner and the link goes to the top left.
The only way to trace it and find the other end is to click the node to get the dotted line visible then scroll the display.
One mistake and clicking in the wrong place, the link goes away and you have to start again.
If the link goes to another tab you click on the tab's name and are (usually) taken to that node.
I'm not exactly sure on the mechanics of how it would be done, but if the dotted line is visible:
RMB on the line would bring up two options.
out and in.
Clicking on the out takes you to the link out
node.
Likewise clicking on the in takes you to the link in
node.
