What is the easiest way get new symbols into Mathematica 9? For example I want to be able to write the Symbol

\mathfrak{A}

that you have in Latex.

I know that you can simply write an "A" in the notebook and change the font, so you get the right symbol. But this way you have to change between the font-window and the notebook window, and find the right font for your purpose.

Favourably I would like to set a new pallet or integrate the symbol in the aliases or set a shortcut like Cmd+Shift+A for the symbol above

I already tried to change the fonts of Mathematica generally, so that the Symbol produces by "Esc A Esc" changes to \mathfrak{A} in Latex, but did not get any satisfying result.

You already have a palette for a great variety of symbols used in math. Just go to Palettes -> Special Symbols. The palette contains the $\mathfrak{A}$ symbol as well.

You can also enter it using esc goA esc, which stands for Gothic A. If you enter symbol using a palette, you can search for it in the docs to find out the shortcut.

Take a look here.

My pallet does contain the Gothic A "๐”„" you posted. When I enter "esc A esc" i do get a letter that fits the style of "๐”„" but does not look quiet the same. I also could not find the letter anywhere else in the documentation center. –  nickel Dec 14 '13 at 17:18
    
Maybe there are missing some fonts? Is there a font package to install to get these Symbols? –  nickel Dec 14 '13 at 17:26
    
esc A esc will give you a capital alpha, not a Fraktur style A. esc goA esc will give you a Fraktur A. It will not be identical to the one you have in LaTeX, but it will be similar. It's a different font. –  Szabolcs Dec 14 '13 at 17:28
    
Are you asking for a way to type an $\mathfrak{A}$ that is 100% identical to the one you get in LaTeX? That might not be easy or convenient. –  Szabolcs Dec 14 '13 at 17:35
    
sry I meant to write esc+goA+esc. Yep thats what I meant. I want to write exactly the Symbol you get in latex when you write the command \mathfrak{A} so this ๐”„. I already tried to just change this letter in the MathematicaFonts.dfont file, you find in /Applications/Wolfram CDF Player.app/SystemFiles/Fonts/TrueType but could not create the format .dfont because my skills in fondforge are not really good. –  nickel Dec 14 '13 at 21:28

I replaced the A in gothic fonts, located at

/Applications/Mathematica.app/SystemFiles/Fonts/TrueType/MathematicaFonts.dfont ,

with the A from the latex fonts and it does produce one error message:

INTERNAL SELF-TEST ERROR: SpanBox|c|2178 Click here to find out if this problem is known, and to help improve Mathematica by reporting it to Wolfram Research.

I can live with that since I am only using mathematica to write at the Moment. Since it is only necessary to replace one family of fonts i can just copy the default family back to its original location to get the old letters.
