I see the two Send Message actions in the Actions page, the four MIDI actions, and out of the six Insert/Display Text actions there is one Display Text action listed. The three Insert actions are there plus an extra "Insert Text" that looks more like an @actions namespace page because it isn't an action itself, it just references the other three Insert actons and also has a link to Type Keystroke, which is not in the Insert/Display menu.
So again, more inconsistencies.
Thanks for the overview. I am not going to attempt any changes at this level until I am a lot more familiar with how it all works and how it's all organized, especially how the Editor Help system links to all this.
Meanwhile, in response to Peter's comment in another thread ...
... I'm going to work on at least putting titles into pages that are missing them.
