Edited for clarification based on comments:

At work we have an old developed program where I need to navigate on a very long dropdown list only with numbered codes. To select the correct code, I manually look at an excel list that shows the code and the name each codes corresponds with.

To make matters worse, it is not possible to type in the dropdown box (only first character is recognized when typing)

So my question is: Are there any program which can show the text from a predefined list, when i mouseover the various possibilities in the dropdown list?

The purpose would be to be able to identify the name which corresponds to each code, without having to look at the excel list.

Thanks in advance!
