// Add needed SCN_MODIFIED flags so your plugin will recieve the notification SCN_MODIFIED of these events for your specific treatments.
// By default, Notepad++ only forwards SCN_MODIFIED with the following 5 flags/events SC_MOD_DELETETEXT | SC_MOD_INSERTTEXT | SC_PERFORMED_UNDO | SC_PERFORMED_REDO | SC_MOD_CHANGEINDICATOR to plugins.
// If your plugin need to process other events of SCN_MODIFIED, you should add the flags you need by sending this message to Notepad++, just after recieving NPPN_READY.
// Add the necessary SCN_MODIFIED flags so that your plugin will receive the SCN_MODIFIED notification for these events, enabling your specific treatments.
// By default, Notepad++ only forwards SCN_MODIFIED with the following 5 flags/events:
// SC_MOD_DELETETEXT | SC_MOD_INSERTTEXT | SC_PERFORMED_UNDO | SC_PERFORMED_REDO | SC_MOD_CHANGEINDICATOR to plugins.
// If your plugin needs to process other SCN_MODIFIED events, you should add the required flags by sending this message to Notepad++. You can send it immediately after receiving NPPN_READY,
// or only when your plugin needs to listen to specific events (to avoid penalizing Notepad++'s performance). Just ensure that the message is sent only once.
