If you want to replace a word that commonly occurs in a document with another
word, you will use this function.
Click on Edit
Click on the double down arrow at the bottom of the menu Click on Replace
Type the word you want the programme to find
for you in the Find what: box.
Type
the word you with which you want to replace it in the Replace with: box.
Click on Find Next
In the example above I am replacing the word magnitude with size.
Once the programme finds the word you are looking for, you
have the choice of ignoring the replace (by clicking on Find Next again),
or you could perform the replace action by clicking on Replace.
