To do a context switch in MacsBug under normal circumstances, do a trap break,
"atb A88F"
which is the OSDispatch (JugglerDispatch is a historic name) trap call.
At location 0x910, you will find CurApName, the current application name.
If you type
"show 910 a"
it'll display the current application name in the upper left of the screen.
To do a context switch, keep typing "g <ret>" until the desired
application is shown.
To remove the trap break, type
"atc"

To get a trashed application to exit, try typing "es".  This should
produce the "unexpectedly quit" dialog box.  If that doesn't work, I
usually reboot the machine.
