Hard carriage returns are entered with alt-enter

Automatic completion of names is done per column (looked backwards)

* FORMULAS:
	
	Operators, cell references, values, worsheet functions,
	and names.

	Arrays:  SUM({1,2,3}*4) gets converted to:
		SUM({1,2,3}*{4,4,4})

** Operators
	
*** Arithmetic

	+, -, /, *, 
	% (percent, as in 20%)
	^ Exponentiation

*** Comparision
	=, <, >, <=, >= <>

** Wierd things
	="1"+"2" yields 3, Excel does the converion to itegers
	="A"&TRUE, Excel convers TRUE to a string: ATRUE

** Display

	Control-` Switches between computed formula display and
	actual formua display

** References
	$ is the absolute cell reference
	R[-2]C	Two rows above, same column
	R[2]C[2] two column down, two right
	R2C2 Absolute reference to B2
	R[-1] Entire row above the active cell
	R current row
	
	=Sheet4!D12+4
	='Miguel is a moron'!A1+2
	
** Functions
