Thanks all for the suggestions, but none would work for me.
I'm torn because I don't like switching programs all the time, but what I really like about FreeCAD is the abillity to specify and work with it's constraints system. Take the capital letter 'T' for example. Before I shear it, the vertical stem might be 1.0 in width, but after shearing, the width of that stem becomes narrower. In FreeCAD, using the constraints system, I could constrain the width of the stem before I shear, ensuring the width of the stem keeps it's width. But without being able to shear, it's pointless me even working in FreeCAD because shear is something used a lot in CAD, I use it myself a heck of a lot.
It's hard to believe a CAD program exists without the ability to shear, I've never known it before, but apparently FreeCAD is such a program, so I can't use it. I have no room to complain, I realise that, but nevertheless I hope they add the ability to shear sketches in the future, because lack of shearing is quite a serious limitation for a CAD program.
I'll just have to check back now and then and hope they add shearing.
