Emacs Manual and Info Pages
Quick info tutorial
Start with C-h i to get into the info pages, then m Emacs RET to get the Emacs info pages. From there, m again and then type some topic of interest, like “spelling”, “hooks” or “tramp”, followed by RET again.
Alternatively, open the Emacs manual directly with C-h r.
Type C-h r or C-h R go directly to the Emacs info pages.
Can switch info pages and go back to the last position you were readign with l.
