Which, "jk" or Caps Lock? The "jk" mapping is just in Vim. As for Caps Lock, if you go to System Preferences, and the Keyboard prefpane, there's a button "Modifier Keys…" in the lower-right corner that lets you remap the modifier keys (including Caps Lock) to other modifiers. So I just use that to remap Caps Lock to Control.
