Input

• Show Key Hints Displays long-press popup hints above keys that have additional characters or symbols.
• Select Hint Source
  Choose where the popup hints (symbols shown above keys) should come from.

  Choose the order of symbols shown when long-pressing a key.
  You can customize this based on typing habits or layout preference.
• Show Functional Hints
  Displays subtle indicators if long-pressing a key triggers special functionality (e.g., emoji panel, layout switch).
• Show TLD Popup Keys
  When typing email or web addresses, this replaces the period (.) popup with top-level domains like .com, .org, .net.
• Pop-up on Key Press
  Briefly shows a preview popup above the key you press. Improves typing accuracy by confirming input visually.
• Vibrate on Keypress
  Adds haptic feedback when pressing keys.
  Toggle this if you prefer tactile feedback while typing.

  Plays a soft sound with each key press.
  You can toggle this for more audio feedback or silent operation.

  Shows the description (name) of an emoji when long-pressing it.

Additional keys

• Number Row
  Adds a permanent number row at the top of the keyboard, regardless of the selected layout.
  Useful if you type numbers frequently and don’t want to switch to the symbols layout.
• Language Switch Key
  Adds a globe key for switching between input languages.
• Language switch key behavior
  Choose what happens when you press the language key:
• Emoji Key
  Adds a dedicated emoji key to quickly open the emoji panel.
  Can be enabled alongside or instead of the language switch key.
• Remove Redundant Popups
  Suppresses popup keys that already exist on the base layout.
  For example: if your layout already includes @, it won’t be repeated in the period (.) popup menu.
