Rush line in internet program (4)
I believe the answer is:
bolt
'rush' is the definition.
(I know that bolt is a type of rush)
'line in internet program' is the wordplay.
I cannot quite understand how this works, but
'line' could be 'l' (used when specifying particular lines from a poem) and 'l' is present in the answer.
'program' could be 'bot' (a computer program) and 'bot' is found within the remaining letters.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for bolt that I've seen before include "Runner" , "A . . . . from the blue is a complete surprise" , "Eat (one's food) quickly" , "Leg it < and consume apace" , "Find a bar" .)
