copied!<p>I didn't list these in my first answer, but in retrospect I've always found them useful, and I often see questions from people which could be easily solved by use of the <code>apropos</code> functions, so I think anything which makes them more visible is a good thing! (I also spotted that <code>apropos-library</code> has appeared since I first added these, so writing this answer was useful to me :)</p> <pre><code>;; Make apropos searches also find unbound symbols, and ;; set new key-bindings for various other apropos commands. (setq apropos-do-all t) (global-set-key (kbd "C-h a") 'apropos-command) (define-prefix-command 'Apropos-Prefix nil "Apropos (a,d,f,l,v,C-v)") (global-set-key (kbd "C-h C-a") 'Apropos-Prefix) (define-key Apropos-Prefix (kbd "a") 'apropos) (define-key Apropos-Prefix (kbd "C-a") 'apropos) (define-key Apropos-Prefix (kbd "d") 'apropos-documentation) (define-key Apropos-Prefix (kbd "f") 'apropos-command) (define-key Apropos-Prefix (kbd "l") 'apropos-library) (define-key Apropos-Prefix (kbd "v") 'apropos-variable) (define-key Apropos-Prefix (kbd "C-v") 'apropos-value) </code></pre> <p>With these bindings, I type <code>C-h C-a</code> whenever I want to search for <em>something</em>, followed by the appropriate character according to the specific kind of search I require (with a prompt to help me if I can't remember the possibilities). If I don't know quite what I'm looking for, then a second <code>C-a</code> (or plain <code>a</code>) at the prompt will run an all-encompassing <code>apropos</code>.</p> <p>If I can't remember what the prompt characters actually mean, typing <code>C-h</code> again at the prompt (i.e. <code>C-h C-a C-h</code>) will list the bindings.</p>
