Work on this will continue at the GitHub issue for this Scribe-Android #16 :)
This is a more involved task. The command buttons for Scribe need to be added above each keyboard. The Scribe key should be in the top left next to the command bar, and when pressing the key these fields should be changed to Translate, Conjugate and Plural buttons that are in the given languages.
First adding the Scribe key and command bar will be done, and afterwards transitioning the interface above the keyboard to the command buttons when the Scribe key is pressed will be done. For now it's not necessary for the settings cog to be removed, as this can be done later.
