# Editors

When editing sources every user has his own preferences which editor to use. XF does not force the user to use one specific editor. To select the editor, chose the menu item (Options | General options). The entry (Editor) allows you to specify a shell command that activates the editor. If this entry is empty the Tk

internal text widget is used. When calling the editor XF

must pass a file name to the editor. The editor command must contain the string ``$xfFileName'' at the position where the filename is to be replaced.

To select the (optional) tkEmacs widget as editor, the menu item (Options | Interpreter options) is chosen. After selecting the checkbutton (Interpreter has the tkEmacs widget), the emacs widget described below is used.
