While working with Microsoft word we have the option to change the text case when ever we wish to change it as per the necessity and the placing of the text. If we start a sentence we will use upper casing for the first letter and small for all the rest, 'I' is always kept used in Upper casing, and some abbreviations are used with uppercase and rest all are printed in small letters or lower casing. Here we will see how we can change the text casing easily.
