# // on_force_close "quit"

# // Send a request for a simplified ui (without arrow fonts) to plugins
# // simplified_ui true

# // Choose the path to the default shell that zellij will use for opening new panes
# // Default: $SHELL
# // default_shell "${nushell}/bin/nu"

# // Choose the path to override cwd that zellij will use for opening new panes

# // Toggle between having Zellij lay out panes according to a predefined set of layouts whenever possible
# // auto_layout true

# // Whether sessions should be serialized to the cache folder (including their tabs/panes, cwds and running commands) so that they can later be resurrected
# // session_serialization false

# // Whether pane viewports are serialized along with the session, default is false
# // serialize_pane_viewport true

# // Scrollback lines to serialize along with the pane viewport when serializing sessions, 0
# // defaults to the scrollback size. If this number is higher than the scrollback size, it will

# // default_layout "compact"

# // Choose the mode that zellij uses when starting up.
# // Default: normal

# // default_mode "locked"

# // Options:
# //   - true (default)
# //   - false
# //
# // mouse_mode false

# // Configure the scroll back buffer size
# // This is the number of lines zellij stores for each pane in the scroll back

# // Valid values: positive integers
# // Default value: 10000
# //
# // scroll_buffer_size 10000

# // Provide a command to execute when copying text. The text will be piped to
# // the stdin of the program to perform the copy. This can be used with

# // that will be used by default if this option is not set.
# // Examples:

# // copy_command "pbcopy"                     // osx

# // Choose the destination for copied text
# // Allows using the primary selection buffer (on x11/wayland) instead of the system clipboard.
# // Does not apply when using copy_command.
# // Options:
# //   - system (default)
# //   - primary
# //
# // copy_clipboard "primary"

# // Enable or disable automatic copy (and clear) of selection when releasing mouse
# // Default: true
# //
# // copy_on_select false

# // When attaching to an existing session with other users,
# // should the session be mirrored (true)
# // or should each user have their own cursor (false)
# // Default: false
# //
# // mirror_session true

# // The folder in which Zellij will look for themes
# //
# // theme_dir "/path/to/my/theme_dir"

# // Enable or disable the rendering of styled and colored underlines (undercurl).
# // May need to be disabled for certain unsupported terminals
# // Default: true

# // styled_underlines false
