In rehearsal hurry from beginning to end (3,7)

I believe the answer is:

run through

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

'in rehearsal' is the definition.
'run through' can be an answer for 'rehearsal' (synonyms). I'm unsure of the 'in' bit.

'hurry from beginning to end' is the wordplay.
'hurry' becomes 'run' (running is a kind of hurrying).
'from beginning to end' becomes 'through' (I've seen this before).
'run'+'through'='RUN-THROUGH'

Can you help me to learn more?

(Other definitions for run through that I've seen before include "To transfix with sword" , "Rehearsal" , "Have a stab at" , "blow" , "very little time in practice?" .)
