TLS Host glob format?

I was looking at using an expression in TLS Host but I can’t get it to work. I press TAB then I get the following possibilities:

"  $  ?  [0-9A-F]  \  _  a  b  f  n  r  t  v

$ = end of string
? = one or zero characters/signs/figures
[0-9A-Z] = in a range
\ = escape character
_ = used in domain names
a =
b =
f =
n = (maybe newline)
r = (maybe return)
t = (maybe tab)
v = (maybe vertical tab)

I really don’t know were a b f n r t v are standing for.

A simple line with tls-host=“^www\.mikrotik\.com$” seems not to work despite the packet (TCP) is not fragmented. Working is

www.mikrotik.com

I am missing grouping (aaa|bbb) which would very nice to have.

The page pointed to by the Wiki does not makes me much wiser: https://en.wikipedia.org/wiki/Glob_(programming)

It’s not regexp, and TAB doesn’t show anything here. These work:

/ip firewall mangle

add action=log chain=prerouting dst-port=443 log-prefix=tls-5a-z protocol=tcp tls-host="[a-z][a-z][a-z][a-z][a-z].mikrotik.com"

Thanks Sob but that help is really there if you are on one of the “\” and press tab:

I can enter the characters show by help in terminal (look at the orange $), and it is accepted on enter, but in the Winbox interface shows a blank field.
