Patent number: 10725625Abstract: A method and system. In response to receiving a click on a first link included in a parent webpage being displayed on a graphical user interface (GUI) on which a parent tab associated with the parent webpage is displayed: a new tab corresponding to the first link is created, the new tab is displayed on the GUI, the parent webpage is replaced by a new webpage associated with the first link, and a screenshot of the parent webpage is generated and saved to a tooltip attribute of the new tab. A cursor of a pointing device hovering above the new tab is detected. The screenshot is retrieved from the tooltip attribute and persistently displayed on the GUI. During displaying the screenshot and with the hovering above the new tab no longer occurring, a click on the screenshot is received and in response, the parent webpage in the GUI is reopened.Type: GrantFiled: February 21, 2019Date of Patent: July 28, 2020Assignee: International Business Machines CorporationInventors: Luke Chen, Paige Chen, Ken Liu, Paul Yuan
