How to launch Google Keep from shell? Using command from 
this blog

I want to launch keep from shell.
Yay!  Thanks to a lot of help from Izzy, I was able to extract the name of the launcher activity from Keep's manifest.  So that means that the console command is:

am start -a android.intent.action.MAIN -n com.google.android.keep/.BrowseActivity


It goes without saying to make sure to preserve proper capitalization (casing).  If you want me to find out the names of any of the other activities (so your command launches that activity instead of the main page), just let me know!
