An alias like @@key=`activate "..."` causes a new prompt to show ... use it several times and the console fills up with unused prompts. Is there a way to suppress the new prompt? If not, perhaps there will be in V12.

|WAD, and there's no way to suppress it (nor will there be in v12).
What if a plugin keyhandler used Command(), during command line entry, to
execute something like ACTIVATE ... would that cause a new prompt, or mess up
the current command line?

No new prompt, provided you pass 0 as the second arg to Command(). If you
use the same buffer as the original command line entry, it will definitely
destroy the current command line. If you copy the original buffer to a new
one and use that for Command(), then the only thing you'll mess up is the
batch debugger.

I tried it like this and **did** get a new prompt.
if ( lpKeyInfo->nKey == F7 )
{
WCHAR szCmd[32] = L"ACTIVATE \"V - *\" 2> NUL";
Command(szCmd, 0);
return 0;
}

If you'll forgive an ignorant newbie question: What's the advantage of using Command() instead of Activate_Cmd() ?

None. I didn't even think of it.

Now that I think of it (and having tried it) ... you can't put the "2> NUL" in
ACTIVATE's arguments. Rex, ACTIVATE could use a /q(uiet) option.

I haven't tried it myself, but I imagine it wouldn't be difficult to do your own redirection via DuplicateHandle(). (Just be sure to save the original stderr handle, and put it back when you're done!)

Actually, Command() worked OK (not causing a new prompt) when I added
lpKeyInfo->nKey = 0;
before returning. This actually leaves the command-line-in-progress untouched
so it can further edited and executed.
I'm experimenting with the file viewer "V". I wrote a user tool for V which
gives foreground to V's parent and assigned the tool to F7. With my F7 routine
(previously mentioned, added to a keyhandler already in my 4CONSOLE plugin) I
can switch seamlessly between V and the console, leaving command lines intact
(perhaps if I wanted to copy something from the viewed file and paste it into
the command).
I like this kind of key mapping, in which some action happens invisibly
regardless of the position in the current command line (unlike keystroke
aliases). But implementing it in a way in which the user could specify
key/command combinations would be tedious; I'd need a routine for turning
user-specified key names into TCC's internal key codes (see the end of
TakeCmd.h).

Do **any** commands have an option to suppress error messages? If so, that's
what I had in mind for ACTIVATE.

I agree. A /E or /Ne would be a better choice, matching other commands. But
even those only suppress warnings, e.g., the file to be deleted did not
exist and thus the desired end result was achieved without deletion. If DEL
cannot delete a file (e.g. a DLL that is in use) the error message still
appears. Likewise if ACTIVATE cannot find the process to be activated it
responds with a "window title not found" message. I can conceive of
situations when one wants to suppress this REAL error message (and others,
such as the above failure to delete), currently supported only by
redirecting STDERR to NUL. A "strong no message" would be useful, via e.g.
another suboption for /N.
