I was looking at the sounds in Basic.asn under Tools/Sounds.
I noticed that there is a sound listed in this scheme for "Keystroke" and for "Deletion" which each have a mechanical keyboard sound when you press associated keys.
But when you press the keyboard's space bar, it generates a different, unique mechanical keyboard sound. But this sound doesn't seem to be included on the list of sounds.
Just wondering why the other sounds are listed and this one is not. It's really a trivial issue, but I am curious.
BTW: These sounds are AMAZING! They are so well done that at least for now it makes me want to actually use them. Usually, when sounds come with other programs that trigger with every keypress or something like that, it is the first thing I disable because they become immediately annoying. I don't know how long it will last, but for now I love having these on. It's the first time I have ever enjoyed the sounds. Brilliantly done!
EDIT: Looks like the same may be true of the "Enter" key. Has it's own unique sound but not listed. Also trivial but curious.
