According to the Disability Discrimination Act text in CAPITAL LETTERS is more difficult to read as letters are harder to recognise.
So what do you do if you receive a document of 7 pages all typed in capital letters?
Microsoft Word has a handy function to change case, and if you wanted to change it all - this is what you do:
1. Select all the text (Ctrl +A)
2. Select Format from the menu at the top and then Change Case
3. Select the option you require and click OK
Lower case = makes all text lower case
UPPER CASE = makes all the text CAPITAL LETTERS
Title Case = makes the First Letter Of Each Word A Capital Letter
tOGGLE cASE = swaps your CAPS to lower case and lower case to CAPS
