Learned a new trick this week for navigating code with the New Visual Studio Search Experience which currently is a preview feature in VS2022.
I’ve used this for some time and it’s quite a bit better than the old experience. It also includes code preview which is useful.

So, it turns out you can search for just the capital letters of a filename and it will find the files that matches for you.
As shown in the image - I’ve done a file search for hst and it finds the file HotkeyServiceTest based on the PascalCase.

You can enable the new search experience under Environment => Preview Features:
