Quick course list is a block for Moodle which allows quick searching of Moodle courses, and displays a link to the course page.
It can be a very helpful block for students to search for a specific course especially if you are having a lot of categories and courses on your moodle site. Now the block is updated for Moodle 2.7 & 2.8.
The quick course list block is very similar to the block quickfind list which allows to search for the users from a block.
You can configure the block to search the course names in the Course full name as well as course short name from the settings page of the block (Site Administration > Plugins > Blocks > Quick Course List). You can also restrict the results by category only, if selected, then courses under the current category will be returned from searches on category pages.
