Abstract: A customer browser and an agent browser are connected to each other through a collaboration server, and a Web server is controlled so as to be accessed through the collaboration server. When the browsers and refer to a page, the collaboration server embeds an applet for detecting a change in the page and a client controller for displaying a page corresponding to changed page information of the other party which performs collaboration. When the customer and agent browsers detect the change in the page, the applet is invoked, and the changed page information is sent to the other party via the collaboration server, and the client controller on the other party controls the browser so as to display the changed page.

Abstract: Disclosed is a method which includes displaying a cursor at a predetermined position in a numeric string and editing the numeric string by either one of; (1) inserting a numeral or a symbol at the cursor position, (2) replacing a numeral or symbol at the cursor position or (3) deleting a numeral at the cursor position or deleting a numeral preceding the cursor position. A digit separator is then inserted into the edited numeric string and the resultant numeric string is displayed on a display device. The cursor is then moved to a new position where another editing step is to be performed on a numeral or symbol that is one position to the right of the numeral or symbol that was inserted, replaced or deleted. Another method disclosed includes displaying a cursor for a numeric string alteration operation at a predetermined cursor position in a numeric string that consists of an optional prefix and a numeric portion wherein a digit separator is counted as one character.
