Hello Greg - -
I did not see that "without having to go via Insert / Symbol ??" qualifier when I wrote this in the 2 AM hour, but I did notice that the upper case P chackmark was different and more "checkmark-looking" (how apt) than the actual square root symbol so that was what drove my blind enthusiasm, thanks for your post.
Weather here in SF is cold by California standards, barely up into the high 50's this week, but it'll be sunny and high 60's this weekend just in time for the spring training reports we'll be seeing on TV until April for the Giants and A's. I empathize what many folks in the US midwest and east are dealing with, I lived through 24 years of that in upstate New York and Michigan before moving here in 1983. We have our earthquakes, fires, and mudslides, so it's pick your mother nature poison I guess, no matter where you live.
