I'm making a StringProperty, and I want to make specific key(e.g. Enter-Key, or others) to do some operator. For example, if I type Enter-Key, the strings are changed by upper words.
I found there is 'options=' in StringProperty, and I think using it will be key, but still not find. Many Thanks!
prop = StringProperty(name="Test", options={'TEXTEDIT_UPDATE'})

optionsparameter is meant for that. You'll have to define custom operators, and create custom keymap entries for them $\endgroup$
