What are 'n' and 'q' commands?

[Haoran Liu]

I noticed I could just input in Stata 17 with simple letters 'n' or 'q'.

I'm curious to know what the full names of these two commands are?

It's noisily and query:

 which n
built-in command:  noisily

. which q
built-in command:  query

The others one-letters are describe, exit, generate, help, list, m (a time-series function replaced by tm()), and use.
