How can I map an option action (Mac keyboard) to a JTextField?

The UI divider for Mac OS X for JTextField

doesn't snap alt ↑to anyone Action

. You can bind a combination to any action you choose. As shown in How to Use Key Bindings , the example below binds alt ↑to an existing "caret-begin-line"

one defined for JTextField

, which moves the cursor to the beginning of the line.

final JTextField jtf = new JTextField("Test");
jtf.getInputMap().put(
    KeyStroke.getKeyStroke(KeyEvent.VK_UP, KeyEvent.ALT_MASK),
    "caret-begin-line");

      

        
        
        
      

    

More examples can be found here . As shown in the Key Binding Utility provided here , JTextField

binds the following actions WHEN_FOCUSED

by name to the specified keys.
