People have come up with variants on "incremental searches" (though nobody, as
far as I can recall, called them that) since the beginning of XyWrite --
probably if you poked around in XySearch, you'd find four or five. Wasn't that
WordStar's way of searching? I never much liked the idea (it always struck me
as craven "isn't that cool" gimmickry), but I put a tiny one in my private part
of U2 which cobbles together several public routines, to do a fairly meticulous
job. To use it, formulate your search$ on the CMline, using any switches from
the native SE[A]rch command -- /F /T whatever -- but call it "ISE..." instead
of "SE...". When you've stated enough of the command (obviously, the command
itself (ISE[A][/switches]), plus some part of the \search_string\) and are
ready to execute it, hit the Helpkey, and keep adding chars until you get where
you're going. Escape to stop adding chars (to quit). Handles 1-, 2-, and
3-byte chars in the search $tring. You can edit the string, backspace, etc.
You could also make it pop a generic opening search template if you wanted,
like a command and some delimiters, and position the cursor between the
delimiters ready for more input; but I never bothered. What counts for me is
proper handling of three-byters, like tildes and so forth.
