Regex help please (to find all items which begin with "plus" sign)

[burgundy]

How do I write a regex to find all items which begin with this "plus" character:

+

I am able to write a regex for all items which begin with this "equals" character:

=

The regex is:

^=

However using this same syntax and substituting the + character does NOT work. This is what fails:

^+

[void]

+ is a special regex character.
+ == match the previous element one or more times.

Please escape special regex characters with \

Please try the following regex:

^\+

Special Regex characters are shown under Help -> Regular Expression Syntax.
