Blackboard characters in Espanso, such as 𝔸 or ℤ or ℂ
\\bb followed by the character you want to write in blackboard font. For example:
\\bbA → 𝔸
\\ double-slash is chosen to avoid this colliding with LaTeX commands.
Hi! I'm Federico, the creator of espanso. I developed espanso in my (little) spare time and I decided to make it open source because I thought it could be useful to many people.
If you liked the project, please consider making a small donation, it really helps :)
