Inserting a Thin Space
I often hear typesetters complain that Microsoft Word has no way to set a thin space, which is usually half the width of a standard space. Using WordSetter, you can insert a thin space by clicking the thin space button on the WordSetter Special Characters toolbar, or by holding down ALT + CTRL and pressing the spacebar. WordSetter gets the point size currently applied to the text, divides it by two, and inserts a space formatted with the new point size.
Remember that using WordSetter to adjust spacing between words overwrites spaces, which means you should insert thin spaces only after using the Set Word Spacing program.
