Menu sound effects other than <scrollsound>?

[KNGAlive]

I mistakenly put this in the wrong forum before, i believe this is the correct one.

Hello, im reasonably new to this but i am learning fast. As hard as it is to find results for issues ive had with my retropie, i usually manage to scrape enough information together from multiple sources to resolve them. As many times as ive avoided asking here it seems its finally my last resort for my current predicament as i can not find proper results while searching. Thank you kindly and im glad to formally be a part of this community. Im enjoying the tinkering more than the games!

My problem is that i would like to add sounds while in the menus for a theme ive built from scratch but only can manage to get the <scrollsound> tag to work. I have seen different variants within different themes yet none of these themes has sounds working for anything other than <scrollsound>.

Here are two tag variants ive seen that do not work regardless if they are within <textlist> tags or not:

    <sound name="systemscroll">
	<path>./PATH.wav</path>
</sound>

    <menuScrollSound>./PATH.wav</menuScrollSound>

Is there a list of the correct sound tags and what would be the proper way to implement them? Im looking to implement sounds such as system scroll, system select, launch and return.
