Abstract: The disclosed method enables a computer system user to efficiently modify attributes of objects displayed by the system and its software applications. Upon selection of a displayed target object by a user, a pop-up menu appears containing a ‘Set Attributes to . . . ’ option. Upon selection of that option by the user, the system cursor changes appearance, and the user is allowed to locate and select a source object separate from the target object (potentially, in a stored file or display window separate from the file and window containing the target object). Upon selection of the source object by the user, the attributes of the source object are immediately transferred to the target object, the display window containing the target object reappears (if it had been hidden by the action of locating the source object), and the display cursor appearance reverts to its normal form.

Abstract: A method, system, and program product automatically determines that a communication request addressed to a remote data processing system may be expected and, in response, automatically establishes a connection to the remote data processing system, thereby causing the time interval for establishing the connection to elapse prior to transmission or reception of the communication request. Thereafter, a communication request is forwarded to the remote data processing system via the connection.

Abstract: Methods for selectively displaying portions of a hierarchical data set on an electronic display comprise the steps of displaying at least a portion of the hierarchical data set on an electronic display in a tree diagram format. Input may then be obtained from a user to identify one or more displayed nodes in the tree diagram that are to be hidden and/or one or more hidden nodes in the tree diagram that are to be displayed. Based on this input, at least one node in the tree diagram is partially collapsed and/or at least one node in the tree diagram may be partially expanded so as to display the hidden nodes identified by the user and so as to hide the displayed nodes identified by the user.

Abstract: A user may easily select a desired day and month in an electronic calendaring system. The user selects a number representing the desired day from a calendar displayed by the electronic calendaring system. The user is then automatically presented with a list of all the months of a year. The user then selects the desired month from the list, and the user is presented with a visual representation of the desired day and month. The user may select the number representing the desired day by right clicking with a pointing device. Additionally, the automatic presentation of a list of all the months of a year may comprise presenting the user with a pop-up menu.

Abstract: A method and system for automatic electronic mail address maintenance in a data processing system coupled to an electronic mail distribution system. An electronic mail processing application is utilized to process electronic mail transferred to or received from the electronic mail distribution system. Each time an electronic mail item is processed within the electronic mail processing application, electronic mail addresses are automatically retrieved and stored within the data processing system. Group or alias address are resolved by automatically accessing the electronic mail distribution system to obtain the appropriate electronic mail address. The retrieved electronic mail addresses may then be displayed by a user together with or separate from an existing address list. These automatically retrieved electronic mail addresses may then be viewed alphabetically, in data sequence or by frequency of transmission or receipt to or from designated electronic mail addresses.

Abstract: A method for distinguishing recipients of electronic communication on a data processing data processing system utilizing the recipient's electronic addresses. Electronic communication is first addressed to at least two recipients with corresponding recipient addresses. The security of the communication is enhanced by enabling the sender to encrypt the communication of selected recipients from among a larger number of recipients being sent the communication simultaneously. The selected recipients e-mail address are tagged and when the sender selects the transmit (or send) option on the e-mail GUI, the communication for those tagged addresses are first encrypted (via an encryption engine) before being transmitted to the recipients. The recipient may also be sent an encryption key to decrypt the communication. Otherwise, the encryption key may be a private key associated with the particular recipients address and stored on the recipient's system.

Abstract: A method and system for generating variable modality child windows. An application is executed utilizing a graphical user interface (GUI) which enables a parent window. One or more child windows may be available to the user during execution. The level of modality of the child window is determined during programming by the application developer. The operating system is modified to permit a variable level of modality during application execution. The developer selects variable modality for one or more of the child windows. When the child window is opened, the user is allowed to interact with the other windows based on the developers determination of level of modality. The variability may be either application or system-wide. The user is thus permitted to interface with only some of the functions on the other windows on the desktop while the child window is open.

Abstract: A method and system for efficiently dismissing displayed message windows or dialog boxes in a data processing system which includes a graphical pointing device and a moveable cursor controlled by physical movement of the graphical pointing device. Each time a message window or dialog box is displayed, the position of the moveable cursor is monitored. A slight oscillation or “wiggle” in the position of the moveable cursor is then utilized to dismiss the message window or dialog box, eliminating the requirement that specific elements within the display be selected by the user in order to dismiss the message window.
