Kate, is QuickCalc in LT? If so that might make for a good read on your blog.
It is indeed, and although I've posted on how to open & close it, I haven't posted yet on how to use it. Good idea.
Did you know you can set variables in QuickCalc by simply entering '$var=20'. And recall the variable using '$var+100'.
Is this different from the stuff you can store in the Variables pane?
