And yet, despite how much I like LyX, I keep using real LaTeX instead -- especially when there is complex maths. That's because the ability to create macros in maths eventually outweighs everything else readability-wise.
And I'm afraid the same logic applies to AsciiMath. Is there some equivalent to
\newcommand[1]{vr}{\mathbf{r_#1}}
Or am I just going to have to use somethng `bb"r"_1` for every instance? That's a lot less readable than `\vr1`.
