Escape Sequence Index (The GNU Troff Manual)

## Appendix C Escape Sequence Index

The escape character, `\` by default, is always followed by at least one more input character, making an escape sequence. Any input token `\X` with X not in the list below emits a warning and interpolates glyph X. Note the entries for `\.`, which may be obscured by the leader dots, and for `\`RET`` and `\`SP``, which are sorted alphabetically, not by code point order.
