- No, the TSR does not capture the keystroke, and in any case the Windows
- System VM gets all keystrokes first and then passes them to the DOS Box.
- Since no keys (such as ALT-TAB) are reserved in the DOS prompt PIF,
- Windows should see and trap the ALT-TAB and switch tasks (which it does
- before the TSR is loaded).

-
- After trying to ALT-TAB out of the DOS Box task, and I then exit from the
- DOS Box, I end up being switched to the next task instead of ending up in
- Program Manager. So Windows must have buffered the ALT-TAB, and not used
- it until I exited the DOS Box.
