Word 2013’s Change Case function quickly switches the capitalization of selected text without requiring manual retyping of the passage. This function is helpful when pasting ill-formatted text from other sources, or you might simply rethink, for example, your decision to scream your words with all caps.
There are several options available in the Change Case menu. Learning what each one does can help you select the best one for your needs.
1. Select the text you want to change.
2. Click the Change Case button on the Home tab’s Font group to see a drop-down menu of available options.
3.Click the option that best suits your needs. The available options are as follows:
Sentence Case changes the capitalization into standard sentence case, in which the first character is capitalized, but the remaining text is lowercase. If your selected text doesn’t include the beginning of a sentence, the result is effectively the same as lowercase.
Uppercase changes the selected text to all caps.
Capitalize Each Word capitalizes the first letter of each word with the remaining letters in lowercase.
Toggle Case changes any uppercase letters to lowercase and vice versa. If you select this option twice in a row, it’s the same as not selecting it at all.
Half-Width/Full-Width are not really capitalization options. Instead, they change the character encoding to single- or double-byte characters, which is useful for some foreign language characters that benefit from the larger, double-byte characters, such as Japanese or Chinese. If you select Half-Width on normal, English text, nothing changes. However, selecting Full-Width significantly increases the character size and spacing.
If you do select Full-Width, selecting Half-Width will change it back to normal text.
