Special Keys (CTRL, SHIFT, ALT, F7, F10, etc.)

[evbo]

I am trying to send special keyboard keys such as:

ALT = '\ue022'

dk = sikuli.DesktopKeyboard() dk.keyDown(ALT)

But what are the key constant values? I assumed they were here: http://doc.sikuli.org/javadoc/constant-values.html

But my above example is not successful. What should I be using/referencing?
