I think that some things could be made default in ToggleActionMenu, and some aspect hidden as well e.g. manage the QActionGroup internally without having the user have to manage it and set the action eveytime.

  Right. Haven't noticed that the mouse modes are more than three.

  I think that this is more a bug than a feature. Adding `action->setActionGroup( selectableActionGroup() );` as first command of `addAction()` would make the action group and all the related methods work e.g. `actions()`.

  Not clear what you mean here.

  Maybe not.
  
  What I am probably not understanding is. Is `ToggleActionMenu` meant to be a general component that you want to use in other parts of KDE? Or is it just meant for Okular? If it is only used in Okular, where do you plan to use it besides than for the mouse actions? 
  What are the other modes in which it could work, besides the one presented in D21971 <https://phabricator.kde.org/D21971> i.e. as a replacement of ToolAction (basically a cleaner implementation of it).
  
  I never used KActionMenu so maybe I am missing something and creating an unuseful fuss :-) Thanks for the patience.
