This tool allows you to Reverse Equal Expression, i find it helpful when you need to fill in objects properties from variables or another object properties then you need to fill them back to variables.
Sample:
txtFullName.text = strName;
txtAge.text = strAge;
now you want to get data in the save button handler all you do is select all the code above at once and then right click and chooseReverse Equal Expression and new code will be ready to be pasted from Clipboard!.
