    text
    copied!<p>I am trying to bind <code>M-&lt;up&gt;</code> and <code>M-&lt;down&gt;</code> to <code>scroll-down-line</code> and <code>scroll-up-line</code> respectively as indicated here: <a href="https://stackoverflow.com/a/16229080/562139">https://stackoverflow.com/a/16229080/562139</a>.</p> <p>This is what I have in my <code>.emacs</code>:</p> <pre><code>;; Key bindings (global-set-key (kbd "M-g") 'goto-line) ;; Scroll line by line (global-set-key (kbd "M-&lt;down&gt;") 'scroll-up-line) (global-set-key (kbd "M-&lt;up&gt;") 'scroll-down-line) </code></pre> <p><strong>Problem:</strong> The scroll key bindings are not taking effect, while the one for <code>goto-line</code> does.</p> <p>When I run <code>M-x scroll-down-line</code> however, emacs prompts me and says </p> <blockquote> <p>"you can run the command with &lt;M-down&gt;"</p> </blockquote> <p><strong>Note:</strong> When I run <code>global-set-key (kbd "M-&lt;down&gt;") 'scroll-up-line)</code> or <code>(global-set-key (kbd "M-&lt;up&gt;") 'scroll-down-line)</code> directly in the mini-buffer, the bindings take effect! However, I seem to have noticed through the corner of my eye when I do the latter, that pressing <code>M-&lt;up&gt;</code> actually sends something like <code>ESC ESC-&lt;up&gt;</code>.</p> <p>I'm foxed. What gives?</p> <p>Note: I am running emacs 24.3 in a terminal (via iTerm on OSX with Option key mapped to ESC+) over SSH to a RHEL5 virtual machine.)</p> <hr> <p><strong>Update</strong></p> <p>I followed the suggestion in <a href="https://stackoverflow.com/a/4351584/562139">this answer</a> and found that pressing M-&lt;up&gt; results in something completely different:</p> <pre><code>ESC &lt;up&gt; (translated from ESC M-[ A) runs the command scroll-down-line, which is an interactive compiled Lisp function. It is bound to &lt;M-up&gt;, ESC &lt;up&gt;. (scroll-down-line &amp;optional ARG) </code></pre> <p>I'm going to try binding that key sequence to the function and check the result.</p>
