10 The Interactive Editor
10.2 Invoking the editor and displaying files
The editor window lets you read and edit text files stored in your filesystem. You can invoke the Functional Developer editor in a variety of ways:
- Click the New Text File (
) button on the main window and a blank editor window opens.
- Double-click on a file listed in a project window and an editor window opens and displays the file.
- Click the Edit Source (
) button on the debugger window and an editor window opens on the file containing the source code that is displayed in the debugger's source pane.
- Choose a file name from the File menu on a project window, an existing editor window, or the main window. (The main window's File menu only lists files if they have been viewed previously.)
- Choose Edit Source from the popup (shortcut) menu for an object.
When the editor opens, a buffer containing the text of the current file is displayed, and you can move around it and change its contents as you wish, then save it back to the original file (assuming that you have permission to write to it). Figure 10.1 shows a file opened in an editor window.
