### 2.4.3 Cfg menu

The Cfg menu contains commands that are used to set the behaviour of Xcas. This menu contains the following entries:

CAS configuration
  — This opens a window that allows you to configure how Xcas performs calculations (see Section 2.5.7). This is the same window you get when you click on the status line.
Graph configuration
  — This opens a window that allows you to configure the default settings for a graph (see Section 2.5.8). This includes such things as the initial ranges of the variables. Each graph also has a cfg button to configure the settings on a per graph basis.
General configuration
  — This opens a window that allows you to configure various non-computational aspects of Xcas, such as the fonts, the default paper size, and the like (see Section 2.5.9).
Mode (syntax)
  — This changes the default syntax (see Section 2.5.2). By default, Xcas uses its own syntax, but you can change it to Python syntax, Maple syntax, MuPAD syntax or TI89 syntax.
Show
  — This displays parts of Xcas.
  DispG
    — This shows the graphics display screen; which has all graphical commands from the session together on one screen.
  keyboard
    — This shows the on-screen keyboard; the same as clicking on the Kbd button on the status line (see Section 2.2, item 2.2).
  bandeau
    — This shows the menu buttons at the bottom of the window; the same as clicking on cmds on the on-screen keyboard (see Section 2.2, item 2.2).
  msg
    — This shows the messages window; the same as clicking on msg on the on-screen keyboard (see Section 2.2, item 2.2).
Hide
  — This hides the same items that you can show with Show.
Index language
  — This allows you to choose a language in which to display the help index.
Colors
  — This allows you to choose colors for various parts of the display.
Session font
  — This allows you to choose a font for the sessions.
All fonts
  — This allows you to choose fonts for the session, the main menu and the keyboard.
browser
  — This allows you to choose a browser that Xcas will use when needed. If this is blank, then Xcas will use its own internal browser.
Save configuration
  — This saves the configurations that you chose with the Cfg menu or chose by clicking on the status line.
