This invention provides the word processing function of the Tab key for users with data processing backgrounds. The Tab key on the IBM Displaywriter and the Field Advance key on the IBM 5251 display station occupy the same relative position on the two keyboards, but the function performed by these keys is significantly different. Pressing the Tab key on the Displaywriter causes a tab character to be inserted into the text (which creates a tab field) and the cursor is moved to the first position of this tab field. If data exists on the line, inserting a tab character in this manner can cause rather dramatic shifting of data to the right. Once a tab field has been entered, the way that data is displayed on the screen is determined by the corresponding tab stop.
