1. Quick skim of the start. <thought>This looks interesting, and even worth saving for later detailed review</thought>
2. I go to save the page. Search box opens and starts filling out with the name of the directory I was pre-typing to save into.
3. <thought>I must have clicked unintentionally. Or mis-hit the tab key? Strange; I don't recall it. Try again.</thought>
4. Same result.
5. ?!$$@?. Test to be sure.
6. Confirmed. <thought>They have bound cmd-s to give the search box focus instead of allowing the user to save (seemingly unintentionally; ie due to 's' being pressed without recognising that a modifier key was also pressed)!</thought>
7. Cmd-W. Window closes. Not saved.
8. <thought>Nope, they didn't also overload 'w'</thought>
I will not take pointers from a site that messes up UX as badly as this. Anything I don't recall from a quick skim is not going to be worth using.
