| | 45 | In the above code the programmer used the same variable name in several scopes. |
| | 46 | We would like to replace the one in the middle where $x is 42. We cannot replace it |
| | 47 | based on selection as that would rename the internal variables ($x = 19) as well. |
| | 48 | |
| | 49 | We can select one of the occurrences of $x that we want to replace, right-click on the mouse, |
| | 50 | select "Lexically Rename Variable", type in a new name and click OK. It will |
| | 51 | replace the correct variable (Once the bugs reported in #565 are fixed). |
