The Hanko plugin allows users to register and quickly paste frequently used text within Obsidian. It provides multiple ways to access saved text, including the right-click menu, command palette, and ribbon menu, making it easy to insert pre-defined content in notes. Users can manage stored items by reordering or deleting them through the plugin settings. Additionally, the plugin supports cursor placement after pasting for enhanced workflow efficiency. While it works seamlessly in edit mode, some features may be limited on mobile devices due to software keyboard restrictions.
