Unfortunately, they don't seem to expose it as a search checkbox for the end user. You can't even use the "OK to highlight" text in the search box because while the phrase does appear in the job posting, it's one of the "notices," like "do NOT contact us with unsolicited services or offers," that appears at the bottom and is not treated as part of the body of the posting for search purposes (if you search for "OK to highlight" you may find some matches from people who just copied and pasted the contents of a previous posting into a new one so the phrase is a part of the posting body). The highlighting is "for non-profit, community-based organizations in your area that help employers meet their needs for diversity and outreach by referring pre-screened, qualified candidates with disabilities for your job openings." Those organizations can add value by finding jobs that are a better match for people with particular disabilities, e.g. there are jobs that are vision-dependent that you could do well but would be difficult to impossible for someone who is blind. Still, I wish Craigslist would add a checkbox to their search that anyone can use.
