	;-> Screen Buffer
	#SU$ = "S" ; Scroll text up by <n>. Also known as pan down, new lines fill in from the bottom of the screen.
	#SD$ = "T" ; croll down by <n>. Also known as pan up, new lines fill in from the top of the screen.
	
	
	;-> Buffer ?
	#ED$ = "J" ; Erase in Display
	#ED_0 = 0  ; Clear from cursor to end of screen
	#ED_1 = 1  ; Clear from cursor to beginning of the screen
	#ED_2 = 2  ; Clear entire screen (May move to 0:0)
	#ED_3 = 3  ; Clear entire screen and lines saved in the scrollback buffer. (Does not work on Windows as of 21H1 in Windows Terminal)
	
	#EL$ = "K" ; Erase in Line
	#EL_0 = 0  ; Clear from cursor to the end of the line.
	#EL_1 = 1  ; Clear from cursor to beginning of the line.
	#EL_2 = 2  ; Clear entire line.
	
	;-> Queries
	#DECXCPR$ = "6n" ; Emit the cursor position as: ESC [ <r> ; <c> R Where <r> = cursor row and <c> = cursor column
	
	#DECSC$ = "7" ; Save Cursor Position in Memory**
	#DECSR$ = "8" ; Restore Cursor Position from Memory**
	
	#RI$  = "M" ; Reverse Index – Performs the reverse operation of \n, moves cursor up one line, maintains horizontal position, scrolls buffer if necessary*

	#ANSISYSSC_DECSC$ = "s" ; Save Cursor – Ansi.sys emulation	**With no parameters, performs a save cursor operation like DECSC
