Sometimes.  I'm not really sure what your original question is asking
though - do you mean changing which application has focus in a desktop
environment, or changing which program is running on a command line, or
something else?

It sounds like you might want to script the window manager or desktop
environment - that's going to work differently on each WM/DE combination
- consult the WM and DE docs for initial info, see if they have Perl
bindings.
