Once the desired portion of the text is selected then depending on the need any one of the following buttons are clicked:

The same can also be achieved by clicking on format → character Alternatively Control + B, and Control + U keys can be used to make the selected text bold, italic and underlined respectively.

A color palette is displayed from which the required color can be selected. Alternatively, select the text and click on the Font color icon, to apply the current color of the Font Color.

Paragraph Alignment

Paragraph alignment refers to the appearance of the left and right sides of the paragraph. By default, Word aligns paragraphs to the left. You can align paragraphs in Word so the right sides are symmetrical. This is called right alignment. You can also align them so you center the lines with even space on both sides. This is called center alignment. Finally, you can justify the alignment, which aligns both the left and right sides. Four types of alignment can be selected, and the best way to make a change is to use the Formatting toolbar. Following steps are used:

• The Format Page option is clicked.
• Click the Page tab, if necessary.
• Select the necessary paper format from the Format drop-down list in the Page. Format section. Or enter the values in the Width and Height spin boxes.
• For changing the orientation Portrait or Landscape radio buttons are used.

• If the ruler is not displayed in the screen, View → Ruler option is clicked.
