Keyboard shortcuts for navigating in tables
After
you select a table, you can use the keyboard to navigate through
it.
In the Contribute editor, do one of the following to
select the table:
If the insertion point is to the
left of the cell, press Shift+Right Arrow.
If the insertion point is to the right of the cell, press
Shift+Left Arrow.
Press the Down Arrow key to position the insertion point

(Mac OS) while the insertion point is in the cell.
To
