Editing and Entering Data
Data is entered into a new or existing variable.
-  Creation
-  of a new variable is by means of choosing 
 Blank Variable  from the submenu New of the menu Data.
- Cursors
-  can be either horizontal or vertical. A vertical 
cursor is for editing one entry in a variable. A horizontal
 cursor is for inserting a new case. 
-  Selection of Cases
-  for copying or cutting a range  of cases is accomplished by dragging horizontally or vertically.
- Pressing Command while Clicking the Mouse
-  allows one to add an additional case to those already 
selected.
- Return

With a horizontal cursor, it does not automatically create an 
empty new case below. Just start typing if you want to create that
new case.
- Tab
-  advances to the next variable in the case if the 
sequence box is active.
