Editor
The flexible editor is a vastly improved version of the current prompt that accepts multiple lines. It allows for insert and delete operations, text pasting or auto-formatting, as well as spell checking and other functions.The editor is highly customizable. To change different aspects of editing, type EDIT-OPTIONS (or simply EDIT-O). If you prefer using a plain editor without all the embellishments, you can also choose to opt out in this menu.
For help on the different commands available to you while editing, you can use the HELP command inside the editor. This is accessible by typing your command character, which is a forward slash (/) by default, followed by the word HELP.
