# Emacs Info Skill

**Trit**: 0 (ERGODIC - documentation mediates between learning and doing)  
**Foundation**: GNU Info + Emacs integration  

## Core Concept

Info is the hypertext documentation format for GNU:
- Structured nodes and menus
- Cross-references between manuals
- Index-based search

## Emacs Commands

```elisp
;; Open Info browser
M-x info

;; Go to specific manual
(info "elisp")
(info "emacs")
(info "org")

;; Search index
M-x info-apropos RET <query> RET

;; Navigate
n - next node
p - previous node
u - up
l - back (history)
```

## Standalone Info

```bash
# Read manual
info emacs
info elisp

# Search
info --apropos=regexp
```

## GF(3) Integration

```elisp
(defun gay-info-trit (node)
  "Return trit based on Info node type."
  (cond
   ((string-prefix-p "Function" node) -1)  ; MINUS: constraint
   ((string-prefix-p "Variable" node) 0)   ; ERGODIC: state
   ((string-prefix-p "Command" node) 1)))  ; PLUS: action
```
