Use Default Editor to specify what default editor File Manager uses to display the text of files that are not specifically bound to another application. If you click SELECT on Other, a text field is displayed in which you can type the name of a different text editor application. If you specify a different text editor that does not display its own window, you must specify that a Shell Tool is started before the text editor.
Running command line programs, such as rm or rlogin, without specifying a Shell Tool to run the program in can lead to unpredictable File Manager behavior. Unless a program starts with its own window (such as textedit or mailtool), prepend shelltool to the program in the Default Editor text field, as shown in Figure 2-45.
