Needing help with swedish braille table on braille input on screen

So assume I have a thing to write, for example 1c2a or whatever. I am using the swedish table and am therefore not sure if anyone can hesp.
I have heard about some letter sign but have no idea how to type it.

#1 try dots 5-6

In english braille dots 5-6 before a symbol is the letter sign.
must be grade I or uncontracted braille maybe.
Don't know how it will work in swedish.
