I have been using Maya for many years and up to version 2015 I was able to set a hotkey for the command:
SelectToggleModeNameCommand
This single hotkey would allow me to toggle between selection modes: Hierarchy > Object > Component. This was very handy and allows me to quickly edit my model on whatever level needed.
I upgraded to Maya 2016 and I cannot find this command or anything similar in the hotkey editor. I also tried copying my hotkey prefs from Maya 2015 to 2016, but this does not work.
Thank you in advance for your help.
