title: Sublime Text 2 Mac Markdown Preview Keybinding
body: <p>I am having some difficulty setting a simple keybinding in Sublime Text 2, which I have only been using for a few hours.</p>
  
  <p>I managed to install <a href="https://github.com/revolunet/sublimetext-markdown-preview" rel="nofollow">Markdown Preview</a> and learned how to invoke it on a simple markdown text file.  My next desire was to set a simple key binding to bring up the browser preview without having to go through the Command Palette, which I find a bit cumbersome.</p>
  
  <p>The instructions at the above link are fairly clear, and I managed to modify my User Settings as directed, so that they look like this:</p>
  
  <pre><code>// Settings in here override those in "Default/Preferences.sublime-settings", and
  // are overridden in turn by file type specific settings.
  {
      "keys": ["alt+m"], 
          "command": "markdown_preview", 
          "args": 
              {
                  "target": "browser"
              }
  }
  </code></pre>
  
  <p>For some reason, however, ALT-m is not bringing up the preview.  Instead, the greek letter mu gets inserted into my text file.</p>
  
  <p>I assumed this is because of some peculiarity involving the Option key on a Mac, so I experimented with trying to bind it to another key like "f7", but that doesn't seem to work either.</p>
  
  <p>Can anybody think of any gotchas involving keybindings for Sublime Text 2 on MacOS X that I might be overlooking?</p>
