good point.  so let me clarify.  ile recognized the following commands,
some of which are not in the Plan 9 style because they do things the
mouse can easily do, like move the cursor.

what is slightly Plan 9ish about ile is that it "sits between"
the terminal emulator and the shell (or any other cooked-mode program).
this got me thinking that a Plan-9 port of ile could sit between
a rio window and rc (or any other line-at-a-time program).  just
a suggestion.
