“Additional Lines to Search for Regular Expressions” can take effect in other cases, for instance,
a\s*b
can match any number of whitespaces including newlines between a and b.
I couldn’t reproduce this issue :
But test it with this:
Default settings.
Set it to 10000, and disable all the other options.
Add 20000+ empty lines.
Find: ^.$
The Status bar shows the result instantly for the first time.
** But searching it again becomes very slow.
BTW 1:
Quote Character in General page of configuration properties can take several characters, and it is used in “Copy Text in Qutoes” command in the Edit menu.
I am not sure which other controls you are referring to, but please let me know which one should have length limit.
I will think about “BTW 2” and suggestions.
