Debugging error messages

Somewhere in my paper I have an undefined reference. TeXmacs is helpful in alerting me to this by popping up a warning message:

Is there any way to go to the place in the document where the undefined reference is? Otherwise, if the paper is large, then it takes a long time to find where the issue is.

The warning itself is not active: you cannot click it.

Use ‘Tools->References->Fix broken references…’. Or just use the focus bar when you are in a reference to select the menu item to find the next problem
