Apart from the options linked to the app, you can also use two Android™ buttons:
- The Back button lets you go back to previous page / cancel the last action / leave the app. These actions depend on what the developper has set up.
- The Menu button (or the corresponding physical button on your mobile device) can only be used when the developper integrated menu options in its applications. It often corresponds to the app's settings.
The Home button lets you go return to the homescreen while leaving the app running in the background. Go to the following FAQ to close it completely.
According to the app, when you hold your finger on a displayed element, you can open a contextual menu (copy, paste, delete etc...).
