Abstract

A means and method for directly manipulating text on a computer display screen. A selected block of text is first identified for manipulation. After being identified, the selected block of text is highlighted on the display screen using contrasting colors or a reverse video. A text manipulation handle associated with the selected text block is displayed. The user may then directly manipulate the selected text block by positioning a cursor within the text manipulation handle and activating a signal generation device. When this occurs, the selected text block may be moved around the display screen while remaining visible using the cursor control device as long as the signal generation device remains active. A shadow image and insertion marker associated with the selected text block is displayed while the selected text block is moveable. A cutting or copying operation may be selected when the signal generation device is activated. The cutting operation removes the selected text block from the available text leaving a blank area at its original position. The copying operation retains the original selected text block in its previous position in the available text. When the signal generation device is deactivated, the selected text block is inserted or pasted into the available text at the position indicated by the insertion marker. The available text is then reformatted to achieve continuity in the lines of available text.

Claims

In an interactive computer-controlled display system having a processor, a memory means, a display device coupled to said processor for visibly displaying text, a cursor control device coupled to said processor for interactively positioning a cursor on said display device, and a signal generation device for signaling an active and an inactive control state, a process for directly manipulating a portion of text available for display on said display device, said process comprising the steps of:

selecting a block of text from a set of available text, at least a portion of the available text displayed on said display device;

dragging said selected block of text from a previous position to a new position relative to said available text, at least a portion of said selected block of text being visible as said selected block of text is dragged, said movement of said selected block of text being responsive to movement of said cursor control device;

displaying an insertion marker on said display device, said insertion marker specifying the new position in said available text where said selected block of text is inserted in an inserting step; and

said step of inserting, inserting said selected block of text into said available text, said selected block of text being inserted at said new position pointed to by the insertion marker and reformatting at least a part of said available text such that the at least one part of the available text is unobscured by the insertion of the selected block of text and to provide continuity between said available text and said selected block of text.

2. The process as claimed in claim 1 further including a step of cutting said selected block of text from said available text, said cutting step comprising:

erasing said selected block of text from said available text leaving a blank area in said available text at said previous position of said selected block of text, said blank area corresponding to an area previously occupied by said selected block of text, said cutting step being performed after said selecting step.

3. The process as claimed in claim 1 further including a step of copying said selected block of text, said copying step comprising:

retaining said selected block of text in said available text at said previous position of said selected block of text, said retained selected block of text not being responsive to movement of said cursor control device, said copying step being performed after said selecting step.
