Underlining

The underlining commands are somewhat obsolete. The underline-region function actually inserts `_^H' before each appropriate character in the region. This command provides a minimal text formatting feature that might work on your printer; however, we recommend instead that you use more powerful text formatting facilities, such as Texinfo.

Command: underline-region start end

This function underlines all nonblank characters in the region defined by start and end. That is, an underscore character and a backspace character are inserted just before each non-whitespace character in the region. The backspace characters are intended to cause overstriking, but in Emacs they display as either `\010' or `^H', depending on the setting of ctl-arrow. There is no way to see the effect of the overstriking within Emacs. The value is nil.

Command: ununderline-region start end

This function removes all underlining (overstruck underscores) in the region defined by start and end. The value is nil.
