I just wanted to give someone a quick idea without creating a ufo. See what happens?
Two images below are from FL 5.0.2 on Mac.
the background shows the original letter,
I moused the whole contour at the center of the crossbar and interactively back-slanted 30 something degrees.
After undoing the above, I back-slanted the same 30something degrees typed into the transform palette, selecting also "center of selection".
Am I missing something? Does this happen for others? Is there a preference for windows or mac degrees I'm not aware of? ;)
Thanks for any kind of help.
