ActiproSoftware.SyntaxEditor.KeyPressTrigger in WPF

Danny,

Key press triggers in SE4 basically just handled a typed character and if it was entered into a specific lexical state would raise the trigger. You should be able to effectively do the same thing by handling text input events in WPF and using the text snapshot scanning API we provide to look at the token you are at and thus lexical state. If it matches your trigger criteria then take whatever action you would want to do.
