Abstract

An information processing apparatus of one aspect of this invention accepts a touch operation for a display area on which a list of thumbnail images corresponding to documents saved in the information processing apparatus are displayed while displaying the thumbnail images. In a case that the accepted touch operation is a flick operation in a lateral direction (first direction), the information processing apparatus changes a thumbnail image displayed in an area for which the flick operation has been made to that of a different page included in a corresponding document. In a case that the accepted touch operation is a flick operation in a longitudinal direction (second direction), the information processing apparatus scrolls a plurality of thumbnail images displayed in the list on the display area in the direction of the flick operation.
