INKEY observations

[vefatica]

I suppose starting INKEY's unquoted prompt with a / is a no-no (trying to make an option out of it).

inkey /m /x /prompt/ %%key
TCC: (Sys) The parameter is incorrect.
 "prompt/"
Usage : INKEY [/C /D /K"keys" /M /P /Wn /X] [prompt ] %%varname

But this one, first observed by Stefano Piccardi, causes no error message, high CPU use, and is uninterruptible:

inkey /m /x /%char[27]/ %%key

Either of these (below) sort of work except that the prompt isn't seen until **after** the mouse click!

inkey /m /x ^e %%key

inkey /m /x  ← %%key  (Esc entered with Alt0255-Esc)

Yes.

WAD -- you probably have ANSI output enabled, so TCC can't tell that you
want to print a (useless?) escape character instead of starting an ANSI
sequence.

Turn off ANSI if you want to print escapes.

Yes I do have ANSI output enabled. Can INKEY's prompt use ANSI escape sequences
(if done correctly)?

Yes -- all output from all commands (except for direct screen writes
like SCRPUT) can use ANSI sequences.
