How do I change my typing from horizontal to vertical

I am making a chart and I do not know how to make some of my boxes go from
horizontal typing to vertical.

Hi,

Select the Cells that are place horozontally..
Select => Copy

Choose a new cell (Cell where you wish the vertical input to start from)
then choose Paste Special => Transpose.

highlight the cells you want vertical text in first

select format>cells
Click the alignment tab and on the right you can adjust the text from 0 to
90 degrees. You can also select "wrap text" if you have alot of text to type
in one cell. Or you can try shrink to fit.
There are many other options here as far as centering the text or aligning
right or left.
