Whether you're a member of Behance or not, you can browse the Joblist here. On the left, you can search by location, creative field, or company. As you add different criteria, they'll be added to the space above the Joblist and you can add or subtract these Active Filters to improve your search.
Alternatively, if you're just interested in looking for a keyword, you can search in the field above the JobList under the Me Tab.
When you have a list of jobs present, click on the first job to view it. If you'd like to view the next job from that list, click the Right Arrow or press the Move Right button on your keyboard. This will progress through all of the jobs in the list you've compiled.
