1@Section 2 @Title { Margin kerning } 3 @Tag { mkern } 4@Begin 5@PP 6The @Code "@Break" symbol offers a variant of ordinary paragraph 7breaking called @I { margin kerning }, in which small characters 8margin.kerning. @Index { margin kerning } 9that happen to end up at the start or end of a line protrude 10slightly into the margin. This is said to make documents 11look better, particularly in narrow columns. For example, 12@ID @Code @Verbatim { 132i @Wide marginkerning @Break { 14This is a test, just a little test, of 15margin kerning. It should kern small 16characters at the margins. 17} 18} 19produces 20@ID 2i @Wide marginkerning @Break { 21This is a test, just a little test, of 22margin kerning. It should kern small 23characters at the margins. 24} 25in which the comma at the end of the first line protrudes. (For the 26@Code "@Wide" symbol, which produces a two-inch column here, 27see Section {@NumberOf precise}.) 28@PP 29As with most @Code "@Break" options, you probably want this in your 30@Code "@InitialBreak" option, described in Section {@NumberOf paras}, 31if you use it at all. By default there is no margin kerning. To turn 32it off in a context where it is on, use @Code {"nomarginkerning @Break"}. 33@End @Section 34
