9. Hidden features - Helium314/HeliBoard GitHub Wiki

This is a list of features / functionality that may go unnoticed, as it is not explicity mentioned or hinted in the app

• Long-pressing toolbar keys results in additional functionality:

  • clipboard -> paste
  • move left/right -> word left/right
  • move up/down -> page up/down
  • word left/right -> line start/end
  • page up/down -> page start/end
  • copy -> cut
  • select word <-> select all
  • undo <-> redo

• Long-press the Comma-key to access Clipboard View, Emoji View, One-handed Mode, Settings, or Switch Language:

  • Emoji View and Language Switch will disappear if you have the corresponding key enabled;
  • For some layouts it's not the Comma-key, but the key at the same position (e.g. it's q for Dvorak layout).

• When incognito mode is enabled, no words will be learned, and no emojis will be added to recents.

• Sliding key input: Swipe from shift or symbol key to another key. This will enter a single uppercase key or symbol and return to the previous keyboard.

• Hold shift or symbol key, press one or more keys, and then release shift or symbol key to return to the previous keyboard.

• Long-press a suggestion in the suggestion strip to show more suggestions, and a delete button to remove this suggestion.

• Swipe up from a suggestion to open more suggestions, and release on the suggestion to select it.

• Long-press an entry in the clipboard history to pin it (keep it in clipboard until you unpin).

• Swipe left in clipboard view to remove an entry (except when it's pinned)

• Disabled Personalized suggestions in correction settings to clear internal history of typed words.

• Select text and press shift to switch between uppercase, lowercase and capitalize words

• You can add dictionaries by opening the file

  • This only works with content-uris and not with file-uris, meaning that it may not work with some file explorers.

• Not really a feature, but you can restart the keyboard by going to the settings and swiping it away from recents

• Debug mode / debug APK

  • Long-press a suggestion in the suggestion strip twice to show the source dictionary.
  • When using debug APK, you can find Debug Settings within the Advanced Preferences, though the usefulness is limited except for dumping dictionaries into the log.
    • For a release APK, you need to tap the version in About several times, then you can find debug settings in Advanced Preferences.
    • When enabling Show suggestion infos, suggestions will have some tiny numbers on top showing some internal score and source dictionary.
  • In the event of an application crash, you will be prompted whether you want the crash logs when you open the Settings.
  • When using multilingual typing, space bar will show an confidence value used for determining the currently used language.

• Where on disk are the files stored (when having root access) Starting at Android 7, some files and the main shared preferences file are not in the default location, because the app is using device protected storage. This is necessary so the settings and layout files can be read before the device is unlocked, e.g. at boot. The files are usually located in /data/user_de/0/<package_id>/, though the location may depend on the device and Android version.
