Mostly I do not use touch panel. I use mostly mouse. Because mostly test circuit (DUT) is on table and example in this case oscilloscope is behind this DUT.
Just what 2N3055 told it also works with mouse, just click it instead of touch..
Then it is also available if click mouse over bottom Trigger info. It open panel where is now also Force trig. And naturally user can move this small panel to place he want.
Example now I have "Bob Pease" style circuit here around table with some other meters also around it and circuit have also high voltage (just open wires all around and hundreds of Volt, but up to only 1kV in this case) and oscilloscope is just behind circuit so that when I do some adjustments in circuit "on the fly" I do not want turn my head for look signal or adjust scope.
With full mouse control it is really really nice to do work and no need use hand over DUT to adjust(in this case bit danger DUT). And now Force Trig is available just under my finger.
In this test case I need many times wait long long time after signal meet trigger. But sometimes I want look what is going on when no trig. Just click mouse.
