Entering "senio"(?) sign in score.

[Victor]

Hello.
I'm using lilypond 2.10.25.
I need to enter two signs(symbols) into my score, both of them are related to 
dealing with repeats and are standard (i.e. not rare). Unfortunately I don't 
know how those signs named in are english(which is not my native language) 
and I wasn't unable to find a translation\name for them so far :-\, so I 
can't find information in lilypond manual (which is in english) myself. Can 
someone help me with this?
I've found several links with articles (unfortunately, without english names I 
could use), and graphical pictures of those signs.
Here are links to the signs:
1) the first (called something like "senyo"):

2) the second:

which is called something like "lantern" or "lamp" in my language.

After playing the repeat, musician is often supposed to play from the first 
sign to second, then jump to the "coda" section.

Thanks.

With best regards, Victor.
