This section gives short explanation of operator options.
For detailed discussion about "forward" and "backward" search, please read section Introduction.
Operators are split into two groups: Operators1 and Operators2.
Group Operators1 is a "forward" search group.
You can use it to define operators like:
- ! && << >> + - % (...and so on, generally these should be special non-alphanumeric characters)
Group Operators2 is a "backward" search group. You can use it to define operators like:
- and or not (...and so on, in short: operators that look like keywords)
In essence, Operators2 group is just another keyword group, Keyword group 9 if you will. I added it here just for easier use of UDL 2.0 GUI, and for better understanding of how operators work. Users could define the same keyword list in keywords groups 1 through 8 and there would be no difference.
_As demonstrated in picture above, Operators1 are always highlighted, and Operators2 are highlighted only if separated from rest of the code.
