I'm a little stuck... Click here to teach me more about this clue!

'tips on shorthand' is the definition.
'steno' can be an answer for 'shorthand' (I've seen this in another clue). I am unsure of the 'tips on' bit.

I can't explain the rest of the clue.

Can you help me to learn more?

(Other definitions for steno that I've seen before include "US secretary perhaps" , "US typist" , "Old-fashioned secretary" .)

I've seen this clue in The Independent.
