Keyboard Shortcuts for Editing Arrays and Tables
When using keyboard keys to navigate arrays, the navigation takes place in one of four directions:
• Forward Direction
—Cursor moves right from current row position until it reaches the end of the current row. Next, it moves to the first element in the next row down, if any, and so on until it has moved through the bottom row.
• Backward Direction
—Cursor moves left from current row position until it reaches the start of the current row. Next, it moves to the last element in the next row up, if any, and so on until it has moved through the top row.
• Downward Direction—Cursor moves down from current column position to the next element down in the same column, if any, and so on until it reaches the bottom element in the column.
• Upward Direction—Cursor moves up from current column position to the next element up in the same column, if any, and so on until it reaches the top element in the column.
