Can you enable the meta key in Mavericks? According to several help posts (for example), you used to be able to enable the option/alt key to act as a meta key. Can you no longer do that in Mavericks?
This is still possible in Mavericks. Have you looked under Terminal Preferences &gt; Settings Tab &gt; Profiles &gt; Default Profile &gt; Keyboard and then ticked "Use option as meta key" at the bottom?
