Interesting find about <Ctrl-2> and Null.

::
:: Read a keypress representing any character between 0x00 and 0xFF and store

::
:: Calling :getAnyKey will also define the following three variables:

:: getAnyKey.CR = Carriage Return 0x0D, decimal 13
:: getAnyKey.CtrlZ = Control-Z 0x1A, decimal 26
:: The three variables can be defined in advance by calling :getAnyKeyInit.
::
:: The optional /P parameter is used to specify a "Prompt" that is written to

::
:: The optional ValidVar parameter defines the characters that will be accepted.
:: If the variable is not given or not defined, then all values are accepted.
:: If given and defined, then only characters within ValidVar are accepted. The
:: first character indicates whether Null (0x00) is accepted. A value of 1 means
:: acceptance, and 0 means rejection. The remaining characters represent
:: themselves. For example, a ValidVar value of 0YN will only accept upper case
:: Y or N. A value of 1YN will additionally accept Null.
::
:: Linefeed, Carriage Return, and/or Control-Z may be added to ValidVar by
:: enabling delayedExpansion, calling :getAnyKeyInit, and then appending
:: !getAnyKey.LF!, !getAnyKey.CR!, and/or !getAnyKey.CtrlZ! respectively.
::
:: If ValidVar is followed by the optional /I switch, then case of standard
