ways to get a "full" list of intents

within the Shortcut Maker App

(install Shortcut Maker from the Play Store)

Its menu system is a little complicated:

• menu items that are about system-level shortcuts:
  • Intents has a big list of available intents.
  • Settings has a big list of shortcuts to specific 'Settings' sub-screens
    • Settings > App Info provides a shortcut to each apps' "app info" page. Similar functionality is available via In-App > Settings shortcut.
• menu items that are about app-specific shortcuts:
  • Activities has a big list of available activities
  • Inner Link has a big list of TODO
  • In-App has a short list of TODO
  • Requested has... TODO — actually, I'm not sure what this one is
• Split allows you to launch two pre-configured apps in split-screen mode
• Collection is a poor-man's folder. Use Nova Launcher instead.
