proofreading turn off/on?
 

Excel 2007 - Is there a way to turn the proofreading option on/off when you
are typing. For example when I type in "nwe" in cell A1 it automatically
changes to "new" I want it to do this for all other times except for this
one time I want it to say "nwe." Is there a shortcut button I can push to
allow me to enter this without having to go change the proofread options
everytime in Excel? All the other times I want it to change to new if I
mistype it, however I want it to say nwe for the couple times I am typing.
There are other words too that it automatically is changing that I don't want
it to for one time uses.
