what is the function of ribbon in ms word
Ribbon (computing) A toolbar interface, called the "ribbon", has been a feature of Microsoft Word from the early DOS-based Word 5.5 (ca. 1990)[5] and the first Windows-based versions (activated by the "View | Ribbon" menu option[6]), for which early advertising referred to the use of "the Ribbon to replace an endless string of commands to let you format characters by eye instead of memory".[3]
Margin (typography) Margins also play an important role in digital word-processing. The default margins for Microsoft Word from version 2007 onward have been 1 inch (2.54 cm) all around; in Word 2003, the default top and bottom margins were 1 inch (2.54 cm), but 1.25 inches (3.17 cm) were given at the left and the right.[31][32] OpenOffice Writer has 0.79 inch (2 cm) all around.[33] LaTeX varies the width of its margins depending on the font size. By default, LaTeX uses 1.5 inches margin sizes for 12pt documents, 1.75 inches for 11pt, and 1.875 inches for 10ptâ€”relatively large margins. These adjustments are intended to allow a maximum of 66 characters per line, to increase readability.[34][35] However, studies have shown that longer line lengths (more than 66 characters per line) can improve readability.[36][37]
