9.2.5 kern command

The kern command defines a space to insert or remove between two particular characters. The kerning information is written only to the TFM file. It has the form:

kern name1 name2 expr

where name1 and name2 are character names, as in the char command (see section 9.2.2 char command), and expr is the amount of the kern in pixels.

For example:

kern F dot -7.5

would put an entry in the TFM file's kerning table such that when TeX typesets a `F' followed by a `.', it inserts an additional space equivalent to -7.5 pixels in the resolution of Charspace's input font, i.e., it moves the two characters closer together.
