>There's more: while you're editing the form, press Tab. You moved focus to PEM window.

I didn't know that. It would be better if it moved to the next control.

>How do you set focus back to the editing window? Only via ctrl+F1.

I don't mind that, though I admit I'll use the mouse, here, simply because that's the easiest way to choose a control. I do wish they'd used the standard CTRL+F6 key to move between windows.

>> Click on an object in the designer. Move arrows - the object nudges, fine. Press control-arrow. All of a sudden, you've changed a property value in the PEM window.<<

I didn't know about that one! That sounds kinda useful, actually. :)
