MS Equation 3.0: red alpha under square root.
MS Equation Editor 2007/2010: cyan pi with a black border
MathType: cyan big sigma with a blue border
OO.o Math/Libreoffice Math: gray button with black "a" under the square  
root
Kile: blue x red = blue y
LyX: cyan big sigma with a blue border

None of the known editing tools has a cursor symbol on its icon.

I attached something along with this proposal, but I think it's ugly (I am  
not an artist, rather mathematician).

They are derivative work from the existing icons.
