How to modify an attribute

If the type of the attribute is bool or enum:

  1. select the alternative you want

else if the type of the attribute is character, integral, floating point, or string:

  1. input text
  2. press the Return key (NOT the Tab key!)

If the value you input is invalid, The Semel Editor (TM) will popup a dialog box with the warning message: "Invalid value: 'the-invalid-value'". When you click the OK button, the screen redisplays with the attribute's previous, unmodified, value.
