Tk question - how do i bind to multiple events?

I have a text field, and i want to get the value out of it when the user
presses Return or tabs to another field. Currently i'm doing it like
this:

  name_field = TkEntry.new(root)
  var = TkVariable.new("f")
  name_field.textvariable(name_var)
  name_field.pack()

  name_field.bind("Key-Return") { name_field_value = name_var.value }
  name_field.bind("FocusOut") { name_field_value = name_var.value }

It seems like there should be a way to combine these, like

  name_field.bind("Key-Return" || "FocusOut") #doesn't work
  name_field.bind("Key-Return", "FocusOut") #doesn't work either

But these doesn't work. Can anyone tell me how to do this please?

Please use TkVirtualEvent object.

-------------------------------------------------------------------------
virt_ev = TkVirtualEvent.new("Key-Return", "FocusOut")
# or use TkVirtualEvent#add(seq, ...) / TkVirtualEvent#delete(seq, ...)

name_field.bind(virt_ev) { name_field_value = name_var.value }
