The Options menu of the Tabbed Scripting Editor introduced in 3ds Max 2008 contains options to control various behaviors of the Editor as well as commands for fixing line end characters, changing indentation settings and switching between proportional and monospaced font display.
Always On Top - Unchecked by default. When checked, forces the Scripting Editor to stay on top of all windows including other 3ds Max floaters and any other applications.
Vertical Split - Unchecked by default. When checked, the Output Pane will be placed at the right side of the Editor Pane. When unchecked, it will be at the bottom.
Wrap - When unchecked (default), lines longer than the width of the Editor Pane will only be displayed partially. When checked, text lines longer than the width of the Editor Pane will be wrapped and shown as multiple lines, allowing you to see all the text.
Wrap Output - When unchecked (default), lines longer than the width of the Output Pane will only be displayed partially. When checked, text lines longer than the width of the Output Pane will be wrapped and shown as multiple lines, allowing you to see all the text.
Read-Only - Unchecked by default. When checked, the current document will be made read-only - typing into it will be disabled, but you will be able to select and copy text from it.
Fixup Line End Characters - corrects the Line End characters by adding an LF where the line ends with CR only.
Change Indentation Settings... (CTRL+SHIFT+I) - opens a dialog controlling the type and number of the indentation characters.
Indentation settings configured using this dialog only apply to the currently active tab, and do not persist between 3ds Max sessions.
