As far as i understood your problem……you can try this

InputFile

Ref ----2345

Slack---- lmnop

Some other text

Some other text

Some other text

Start ---osdidiu

End ---- llll

Ref ----234513

Slack---- lmnodsasdp

Code

 awk '$1 == "Start" || $1 == "End" || $1 == "Slack----" {print $0}' InputFile

Output

Start ---abcxyz
End ---- efg123
Slack---- lmnop
Start ---osdidiu
