title: How to disable generating special characters when pressing the `alt+a`/`option+a` keybinding in Mac OS (`⌥+a` )?
body: <p>There is a behavior in my mac that I'm trying to disable.</p>
  <p>When I'm in any text editor and typing a key combination using the <code>alt</code>/<code>option</code>+any letter, the output will be special characters.</p>
  <p><em>For example:</em><br />
  the combination <code>alt+a</code> will generate <code>å</code>.<br />
  the combination <code>alt+x</code> will generate <code>≈</code>.</p>
  <p>I want to cancel this behavior.<br />
  I'm a programmer and when I use my code editor I want to map some keybinding (keyboard shortcuts) to the <code>alt</code> key (<code>⌥+a</code> for example) but when I do that it doesn't execute because it generates the special characters.<br />
  I guess that the special character has a priority over my code editor shortcuts.</p>
  <p>Do you know how can I disable this default behavior?</p>
  <p>Thank you</p>
