Keynote supports bidirectional text, so you can enter and edit text written from left to right (such as in English or Chinese) and from right to left (such as in Arabic or Hebrew) in the same presentation. You can also use bidirectional text in table cells, and you can reverse the direction of tables to accommodate different languages.
The direction of text in table cells is based on the direction of the top-left cell in a left-to-right table, or the top-right cell in a right-to-left table. If a cell is empty, its direction is based on the current keyboard (tap to change keyboards).
You can change the direction of text in individual cells, or you can reverse the table format so that header rows, column order, and text direction are reversed.
Reverse the text direction of a cell: Select the text in a cell, then tap 
.
Reverse the table direction: Select a table, then tap .
When you reverse table direction, cell alignment is affected as follows:
Text cells set to auto-align (the default setting) change their text alignment.
Number cells set to auto-align (the default setting) do not change their number alignment. (Numbers always auto-align to be right-aligned.)
If a cell has had its alignment specifically set to be right, left, or center aligned, it retains that alignment.
If a cell has had its alignment specifically set to be justified, the gap for a partial line changes from being on the right to being on the left.
