Note to self: Do not use a watch entry like this while debugging GExperts:
GxOtaReadEditorTextToString(GxOtaGetEditReaderForSourceEditor(nil))
While this might seem very convenient it will sooner or later corrupt the current edit buffer or do something even worse, because, as a comment in ToolsApi states:
WARNING!!!
A IOTAEditReader should never be active at the same time as an IOTAEditWriter.
But having it as a disabled entry in the watch window, enable it to inspect the current content of the edit buffer, before disabling it again can be very useful.
