POHow to set a key with C-x 8 prefix?
text
Body
copied!<p>Say I'd like to re-bind <code>C-x 8 x</code> to <code>ξ</code>. So I do:</p> <pre><code>(global-set-key (kbd "C-x 8 x") (lambda () (interactive) (insert "ξ"))) </code></pre> <p>but it doesn't work: it still inserts the default x sign. Then I tried both:</p> <pre><code>(global-unset-key (kbd "C-x 8 x")) (global-set-key (kbd "C-x 8 x") nil) </code></pre> <p>none gives any effect. </p> <p><strong>Edit</strong>:</p> <p>Here's what I'm using now for Greeks:</p> <pre><code>(define-key 'iso-transl-ctl-x-8-map "a" [?α]) (define-key 'iso-transl-ctl-x-8-map "b" [?β]) (define-key 'iso-transl-ctl-x-8-map "g" [?γ]) (define-key 'iso-transl-ctl-x-8-map "d" [?δ]) (define-key 'iso-transl-ctl-x-8-map "e" [?ε]) (define-key 'iso-transl-ctl-x-8-map "z" [?ζ]) (define-key 'iso-transl-ctl-x-8-map "h" [?η]) (define-key 'iso-transl-ctl-x-8-map "o" [?θ]) (define-key 'iso-transl-ctl-x-8-map "i" [?ι]) (define-key 'iso-transl-ctl-x-8-map "k" [?κ]) (define-key 'iso-transl-ctl-x-8-map "l" [?λ]) (define-key 'iso-transl-ctl-x-8-map "m" [?μ]) (define-key 'iso-transl-ctl-x-8-map "n" [?ν]) (define-key 'iso-transl-ctl-x-8-map "x" [?ξ]) (define-key 'iso-transl-ctl-x-8-map "p" [?π]) (define-key 'iso-transl-ctl-x-8-map "r" [?ρ]) (define-key 'iso-transl-ctl-x-8-map "s" [?σ]) (define-key 'iso-transl-ctl-x-8-map (kbd "M-s") [?ς]) (define-key 'iso-transl-ctl-x-8-map "x" [?ξ]) (define-key 'iso-transl-ctl-x-8-map "t" [?τ]) (define-key 'iso-transl-ctl-x-8-map "y" [?υ]) (define-key 'iso-transl-ctl-x-8-map "f" [?φ]) (define-key 'iso-transl-ctl-x-8-map "v" [?χ]) (define-key 'iso-transl-ctl-x-8-map "j" [?ψ]) (define-key 'iso-transl-ctl-x-8-map "w" [?ω]) (define-key 'iso-transl-ctl-x-8-map "A" [?Α]) (define-key 'iso-transl-ctl-x-8-map "B" [?Β]) (define-key 'iso-transl-ctl-x-8-map "G" [?Γ]) (define-key 'iso-transl-ctl-x-8-map "D" [?Δ]) (define-key 'iso-transl-ctl-x-8-map "E" [?Ε]) (define-key 'iso-transl-ctl-x-8-map "Z" [?Ζ]) (define-key 'iso-transl-ctl-x-8-map "H" [?Η]) (define-key 'iso-transl-ctl-x-8-map "O" [?Θ]) (define-key 'iso-transl-ctl-x-8-map "I" [?Ι]) (define-key 'iso-transl-ctl-x-8-map "K" [?Κ]) (define-key 'iso-transl-ctl-x-8-map "L" [?Λ]) (define-key 'iso-transl-ctl-x-8-map "M" [?Μ]) (define-key 'iso-transl-ctl-x-8-map "N" [?Ν]) (define-key 'iso-transl-ctl-x-8-map "X" [?Ξ]) (define-key 'iso-transl-ctl-x-8-map "P" [?Π]) (define-key 'iso-transl-ctl-x-8-map "R" [?Ρ]) (define-key 'iso-transl-ctl-x-8-map "S" [?Σ]) (define-key 'iso-transl-ctl-x-8-map "T" [?Τ]) (define-key 'iso-transl-ctl-x-8-map "Y" [?Υ]) (define-key 'iso-transl-ctl-x-8-map "F" [?Φ]) (define-key 'iso-transl-ctl-x-8-map "V" [?Χ]) (define-key 'iso-transl-ctl-x-8-map "J" [?Ψ]) (define-key 'iso-transl-ctl-x-8-map "W" [?Ω]) </code></pre>
