Feature request, I guess. That window is sensitive to where the focus
is, but the various parts of drscheme aren't set up to notify the
window when they get the focus (which is why it is modal for now).

Which platform? Windows? For me control-x;o does the trick, but that
probably only works for you if you disable menu shortcuts. The
<menukey>-d and <menukey>-e shortcuts are also useful for that.

c:s:tab and c:tab switch between tabs; I see that c:shift:tab is also
supposed to switch between the definitions and interactions, but
apparently is superseded. Probably best for you to make your own
keybinding; seach in Help Desk for "keybinding" and follow the link
about adding user-defined keybindings (or just go to 3.1.2 in the
drscheme manual).
