Terminal uses the Basedir Specification as defined on Freedesktop.org to locate its data and configuration files. This means that file locations will be specified as a path relative to the directories described in the specification.

${XDG_CONFIG_HOME}

The first base directory to look for configuration files. By default this is set to ~/.config/.

${XDG_CONFIG_DIRS}

A colon separated list of base directories that contain configuration data. By default the application will look in ${sysconfdir}/xdg/. The value of ${sysconfdir} depends on how the program was build and will often be /etc/ for binary packages.

${XDG_DATA_HOME}

The root for all user-specific data files. By default this is set to ~/.local/share/.

${XDG_DATA_DIRS}

A set of preference ordered base directories relative to which data files should be searched in addition to the ${XDG_DATA_HOME} base directory. The directories should be separated with a colon.

${XDG_CONFIG_DIRS}/xfce4/terminal/terminalrc

This is the location of the configuration file that includes the preferences which control the look and feel of Terminal.

${XDG_CONFIG_DIRS}/xfce4/terminal/accels.scm

Menu accelerator map.

Terminal offers a few hidden options to allow power users to control various advanced settings and to reduce the number of options in the user interface. To set any of these options, you will have to open the file ${XDG_CONFIG_HOME}/xfce4/terminal/terminalrc in your favorite text editor and edit the section [Configuration]; simply create the file if it does not already exist. For example, your terminalrc could look like

[Configuration]
MiscAlwaysShowTabs=TRUE
MiscBell=TRUE
MiscConfirmClose=FALSE
MiscCursorBlinks=TRUE
MiscCursorShape=TERMINAL_CURSOR_SHAPE_BLOCK
MiscCycleTabs=FALSE
MiscInheritGeometry=TRUE
MiscMouseAutohide=FALSE
MiscTabCloseButtons=TRUE
MiscTabCloseMiddleClick=TRUE
MiscTabPosition=GTK_POS_TOP
MiscHighlightUrls=TRUE

plus all the options that are controlled through the preferences dialog.

MiscAlwaysShowTabs

If TRUE the tab headers will always be displayed even if only a single terminal tab is open. This option is useful if you do not want the terminal window to resize when you open a second tab. It is disabled by default.

MiscBell

Enables (MiscBell=TRUE) or disables (MiscBell=FALSE) the audible terminal bell. It is disabled by default.

MiscConfirmClose

Controls whether Terminal popups a confirmation dialog when the user tries to close a terminal window with multiple tabs in it. Can be either TRUE (the default) or FALSE.

MiscCursorBlinks

Enable this option to display a cursor that blinks. Can be either TRUE or FALSE (the default).

MiscCursorShape

Specifies the shape of the cursor in the terminal. This can be either TERMINAL_CURSOR_SHAPE_BLOCK (the default), TERMINAL_CURSOR_SHAPE_IBEAM or TERMINAL_CURSOR_SHAPE_UNDERLINE. This option is only available when you compile against VTE 0.19.1 or newer.

MiscCycleTabs

This option controls whether you can circulate through terminal tabs. That is, whether you are able to go from the last tab to the first tab using the Next Tab button from the Go menu (or the associated keyboard shortcut), and from the first tab to the last tab using the Previous Tab button from the Go menu. The option can be either TRUE (the default) or FALSE.

MiscDefaultGeometry

The default geometry for new Terminal windows if no –geometry=geometry option is specified on the command line (defaults to 80×24).

MiscInheritGeometry

This setting controls whether new windows will inherit the geometry (width and height of the active tab) from its parent window (the window from which the new window was opened). Can be either TRUE or FALSE (the default).

MiscMouseAutohide

This setting controls whether Terminal will hide the mouse cursor while you are typing in a terminal window. Can be either TRUE or FALSE (the default).

MiscTabCloseButtons

This setting controls whether Terminal provides a close button with the terminal tab title. Can be either TRUE (the default) or FALSE.

MiscTabCloseMiddleClick

This setting controls whether Terminal will close a terminal tab when the user middle-clicks the tab title. Can be either TRUE (the default) or FALSE.

MiscTabPosition

Specifies the position where the tab headers should be displayed. This can be either GTK_POS_TOP (the default), GTK_POS_LEFT, GTK_POS_BOTTOM or GTK_POS_RIGHT. If you specify GTK_POS_LEFT or GTK_POS_RIGHT here, the tab header texts will be displayed vertically instead of horizontally. It is highly recommended to disable MiscTabCloseButtons for GTK_POS_LEFT and GTK_POS_RIGHT.

MiscHighlightUrls

This setting controls whether URLs – both hyperlinks and email addresses – will be highlighted in the text displayed in a terminal window. If you change this option to FALSE, URLs won't be highlighted anymore and you will no longer be able to middle-click the URL to open it in the preferred application.
