• Word Prediction Dictionaries - Add, remove, or import words and phrases to customize text prediction via a management console.
• Simulation Management - Allows users to toggle keyboard emulation to prevent modifier keys from interfering with mouse actions.
• Automatic Text Formatting - Automatically injects spaces between words and capitalizes the start of sentences during text entry.
• Command Repetition Loops - Allows users to run a set of commands repeatedly or indefinitely until manually stopped.
• Hold Duration Triggers - Simulates holding a key down for a set duration or toggling a key state.
• Input Sequence Automations - Combines text entry, system actions, and timing delays into single key presses for complex automation.
• Virtual Layout Switching - Switch between simplified, alphabetical, or custom layouts to accommodate different typing preferences.
• Keyboard Input Modes - Provides configurations for switching between different keyboard interaction paradigms, including simplified conversation modes.
