This package allows the user to create a menu for fast insertion of arbitrary symbols. Features: * The symbols can be organized in hierarchies. * Most frequently used symbols require only one keystroke, while others are placed in dedicated sub-menus (for example, “arrows”) and can be inserted with two or three keystrokes. * Paired characters like `“”` can be inserted. Normally, the point will be placed between the characters, but if some text is selected, the paired character will wrap it without moving the point.
