kapresley:

Perhaps I could make the docs a bit clearer in my next changes...

Many of the on/off and -/+ options work in a *deferred* manner rather than *real time*. This is mostly to speed up the screen re-draws. For example, you can:

- click 'Messier On'
- click 'Polar Off'
- click 'Planets On'

(or whatever)

...and then when you click the plot screen image, the star plot is re-drawn with all your 'queued up' toggles. Know what I mean? Changing the date/time options -- on the other hand -- re-draws the screen immediately (no queuing).

The idea of 'queuing' makes it a lot faster, since you can change a bunch of options rather than waiting for each one to take effect individually. As another example, you could (for example) click the 'FOV +' repeatedly to queue up a large change in FOV, rather than doing each zoom out individually.

When you use the new hardware key options to do this stuff, no queuing takes place -- it redraws the screen for each action.

I hope this helps to clarify what the docs say
