Does VA actually jump to the upper case MATERIAL, or is it just being highlighted?
Testing VS2022 on a machine where VA has never been installed, and is not installed, I did a case sensitive, whole word match find for "simple", and I get the following result. Note that instances with the wrong case, and part of other words are being highlighted, but IDE Find won't jump to any of them.
Thank you for finding that IDE setting, it certainly makes it easier to see what is coming from VA and what is coming from the IDE. I have put in a bug report for this not respecting the find settings:
