One entry is selected, you can move the selection up/down in the list of choices via the up/down arrow keys, and you can show the help for the selected entry by hitting the <Return> key. Entering 'q' takes you back to the GAP prompt. > 2.

The text in question belongs to the help about 'quit' from the GAP package ITC; the list of choices should contain also entries for 'quit' from the GAP Tutorial and for 'QUIT' from the Reference Manual.
