I'm trying to use Find and Replace in Word to make an entire line or all words on a line Bold, but this is proving to be difficult since using the wildcard * after the search criteria does NOT include all of the remaining words or characters on the line. One thing they all have in common is they all have a paragraph return character at the end of the line, but unfortunately, under Find > Special, there is no option for a standard paragraph return character. Closest I could find was a Manual Line Break, which does not even remotely work.

Any suggestions how I can select the entire line or all content on the line, and then make it bold?

Example of criteria I am searching for in the document:
a.	check 	a. Immerse the burn in cool water.
The search criteria is the following:
check ^t?.*.
There is an intentional space between check and ^t
This works for lines that end with a period, BUT fails terribly for lines that do not end with a period.

I would also like to delete the redundant letter, which is an 'a' in this example, and remove the word 'check', so that all that remains is the following in bold text:
a. Immerse the burn in cool water.
