I have a command defined as

\newcommand{\mb}[1]{\mathbb{#1}}

I was wondering if it is possible to define it in a way that I can write \mbA instead \mb{A}? One way is to define one by one \dbA, \dbB, \dbC, etc. but I hope there is something straightforward to achieve this.

It's perfectly ok, as far as TeX and LaTeX are concerned, to write \mb A, \mb B, \mb C, etc instead of \mb{A}, \mb{B}, \mb{C}, etc. – Mico Oct 01 '22 at 02:38

Why not just \newcommand*\mb{\mathbb} ? – Ulrich Diez Oct 01 '22 at 15:13
@Mico Unfortunately, spacing does not worth not defining \mbA. First, things like \mb A_\mb B does not look nice on editor but more importantly, things like \tilde\mb A does not work. – Jo' Oct 02 '22 at 19:35
@Werner Thank you. I couldn't find the time to check it yet as it does not look very easy but seems like the solution exists. – Jo' Oct 02 '22 at 19:39
@UlrichDiez Then \mbA does not work, right? – Jo' Oct 02 '22 at 19:40
@Jo' No, but \mb A does work. If you want \mbA/\mbB/\mbC/... to work, each of these control-word-tokens needs to be defined on its own. You can define a loop which does that for you, e.g., as shown in the contribution linked by Werner. – Ulrich Diez Oct 03 '22 at 11:25
