Heyo,
it occurs to me that having the ability to apply a unique key-command shortcut to enable/disable the ‘receive keyboard events for this plugin’ icon/feature would be wonderful in reducing the tediousness of having to click that effing icon every time… 
This:
But I suppose I should ask…
-Does a key command already exist for this? Because I couldn’t find one, if so…
This hypothetical shortcut could only work and apply to the current plugin that’s ‘in focus’ (or whatever).
Could this be implemented maybe? Please at least consider. 
Because when mixing, such a thing might be enormously beneficial for cruising around the plugin landscape in the DAW…
Thanks for any comments/suggestions.
-J
