Suppose I have the following macro (the `\mathbb`

result looks better than the builtin `RR`

result)

Now I can type

`\RR`

and enter to get the result. However, I am lazy and want to get the result by typing “RR” only, without the `\`

and `enter`

, just like the builtin one. I already have working keyboard shortcuts such as `("a l" "<alpha>")`

in the math mode, but this does not work for my own macro `("R R" "<RR>")`

.
