Looking for VBA developers (ideally, but not necessarily, existing users of VBE_Extras) who are willing to carry out some testing ... because while I consider myself an expert in VBA and in various other Office applications, I'm certainly not an expert when it comes to Visio or Project.

A declaration can have many references and sometimes you just want to go to the location of the next, or previous, reference of that declaration. That reference might be within the same procedure / property; it might be in the same Module but may or may not be visible on-screen; or it might be in another Module of your VBA Project. The "Next code reference in this Project" and "Previous code reference in this Project" commands of VBE_Extras will do this for you.

When you have a Module with many members (i.e. Module-level declarations such as Consts, Enums, Sub, Functions etc), it can sometimes be handy to just jump through each of those declarations in turn, in the order that they are present in the Module. That is the point of the "Goto declaration above" and "Goto declaration below" commands in VBE_Extras.
