"Completions are supplied, when requested and available, for module names, "

"attributes of classes or functions, or filenames. Each request method "

"displays a completion box with existing names. (See tab completions below "

"for an exception.) For any box, change the name being completed and the item "

"highlighted in the box by typing and deleting characters; by hitting :kbd:"

"`Up`, :kbd:`Down`, :kbd:`PageUp`, :kbd:`PageDown`, :kbd:`Home`, and :kbd:"

"`End` keys; and by a single click within the box. Close the box with :kbd:"

"`Escape`, :kbd:`Enter`, and double :kbd:`Tab` keys or clicks outside the "

"box. A double click within the box selects and closes."
