    # event handler code goes here
end

An array of keys:

event :keypress, :enter, :g do
    # event handler code goes here
end

Having a modifier

event :keypress, :enter, {key: :g, modifiers: :ctrl} do
    # event handler code goes here
end

Having multiple modifiers

event :keypress, :enter, {key: :g, modifiers: [:shift,:ctrl]} do
    # event handler code goes here
end
