I was looking for a way to output a list of all the labels used in the document, but so far have only found this answer that uses a built in function in WinEdt. Is there a similar functionality in MikTex/TeXworks, or will I need to search the file using one of the regular expression and running it in command prompt or something? I'm currently using TeXworks Version 0.6.1 (MikTeX 2.9.6100 64-bit) on Windows 10. Thanks!
So, based on the comment by @DavidCarlisle, I was able to figure out how to search the *.aux file for the labels. First I had to tell TeXworks to show the *.aux file using the instructions found in this question and this question. Then I was able to use PowerShell to search the contents of the file using the Select-String cmdlet based on the instructions here and searching for "label" in the *.aux file.
