Two simple Qs

[Bilal Sana]

Hi there
I am looking for easy way to do below two things.

1. If a line has a certain word/string then delete that line
2. Delete a certain number of characters from the end on each line
   Appreciate if anyone can support
   Thanks

Experiment with the following:

Case 1:

To delete lines containing the text string “yourword”
Find what zone: (?-is)^.*?\Qyourword\E.*?\R
Replace with zone: Make sure this zone is empty!
Search mode: Regular expression

Case 2:

To delete the last 4 (for example) characters from each line:
Find what zone: (?-s).{4}$
Replace with zone: Make sure this zone is empty!
Search mode: Regular expression
Note: A line must have at least 4 characters on it to be affected!
