...  oddly the X-Shift is backwards by modern convention ...

Something I'd never considered before but interesting ...

It really depends what you want the X shift to do - centre the trace on the screen or, if the trace is expanded, move along it to examine various portions of it.

Unlike the Y amplifier, there should be nothing to move the trace from its correctly centred position - no DC shift between measurements, etc.

So, if you want to examine the right hand area of an expanded trace, should you move the entire trace to the left by turning the shift control anti-clockwise or is it more intuitive to move the viewable area to the right (which is, of course, the same thing) by turning the shift control clockwise?

I suppose it's a bit like the difference between a tiller and a steering wheel on a boat!
