How to Disable Line Breaks in a Text Box with Character Rate Limit

[rowise]

I'm working with a text box that has some interesting behavior and settings. The text box has a "Chars/sec" label, and if the character input rate exceeds a certain max CPS (e.g. 25 CPS), the text box will turn red.
Below the text box, there's a "Single line length" label that shows the character count for the first and second lines. If either of these line lengths exceed a configurable max, the label turns red.
The instructions mention that the single line max length can be adjusted in the settings, and that by default, only one line break is allowed using the normal Enter key. To get more line breaks, you have to use Ctrl+Enter.
My question is - is there any way to completely disable or remove the line breaks in this text box, rather than just increasing the max number of lines allowed? I'd like the text to flow continuously without any forced line breaks at all. Is that possible with this text box setup?"
Does this help capture the key points and frame the question in a clear way for an English forum? Let me know if you would like me to modify or expand the wording further.

We’ll at least need the name of the software

Subtitle Edit, I thought this was the official forum for Subtitle Edit.

Sorry, I thought somebody else would answer this (these fora used to be more active). There's a find and replace function in the edit menu (or hit CTRL+H) that can be used to get rid of hard line breaks.

Highlight the subtitle you want to change.

Pull up the find & replace menu

Set the search feature to regular expression

in Find what: put in \n

in Replace with: put in a space

click Replace

or

click Replace all to remove line breaks from the rest of the subs
