# Quicker command for fraktur letters than \mathfrak?

There is a shorthand way of writing letters in blackboard bold: instead of using \mathbb, we use \Bbb. This substantially sped up my time writing questions and answers on math.SE. In the course of composing a question about rings, I started to wonder:

Is there a shorcut way of typesetting Fraktur letters (e.g. $$\mathfrak{a}, \mathfrak{p}$$) that is to \mathfrak what \Bbb is to \mathbb?

I haven't seen one used on the site, but if it exists, it would again speed up my time writing questions & answers. Anyone got an idea?

(Note: I understand that one can define personalized commands at the start of answers, but I'm talking about something that I can use without defining a shortcut, like \Bbb.)

• \frak is similar to \sf or \rm or \bf, and all of those are different from \Bbb. – Asaf Karagila Aug 21 at 6:43
• @AsafKaragila When I use \frak it seems to make everything else in the dollar signs fraktur, even when I only want to apply it to a specific letter. – Rivers McForge Aug 21 at 6:46
• Add brackets ${\frak A}BC$ to get ${\frak A}BC$. – GEdgar Aug 21 at 11:06
• Since there is \mathfrak, why is there no \textfrak ? – GEdgar Aug 21 at 11:41

\frak is similar to \sf or \rm or \bf (they all change the font), and all of those are different from \Bbb (which only affects the next group).
$${\frak F\in A}\quad\text{ vs. }\quad{\Bbb F\in A}$$
