Navigating within a table
Think of a table as being a block of text that happens to contain vertical and horizontal lines. Use the Tab and arrow cursor keys if you don't want to keep reaching for the mouse all the time. To jump from cell to cell, left to right along a row and top to bottom, press the Tab key. To go in the reverse direction, press Shift+Tab.
The Right arrow key follows the same direction as the Tab key but stops at each character. Similarly, the Left arrow key follows the Shift+Tab key. The Up and Down arrow keys move up and down columns. Note that if you start from outside a table, the Down arrow key will move down the leftmost column and the Up arrow key will move up the rightmost column.
