Is it possible to only rename instances of a variable that appear in the code after the point at which you edit the variable selected? (shift+enter)

I want to change the names of all variables that share a common name, but only after a certain point.

v1 = 2
x = v1 + 3
y = v1 + 2
z = v1 + 4

in the code above, if I replace the name of v1 in line 2 with v2, and press shift + enter, it replaces every v1 to v2.

Is there a way for it to leave all lines of code above the current line unchanged?

Thanks

I dont think so, please clarify, replace the v1 with v2, during execution the program?

 v1 = 2
x = v1 + 3
y = v1 + 2
z = v1 + 4
% Finished the all operation with V1 then only you can change v1 to v2 in desired line
x=v2+...

The question is about replacement in the editor.

Suppose you are editing some code and you duplicate a block of text and wish to rename a variable inside the block, but do not wish to rename the variable in the original copy (and everywhere else it was used.)

It would certainly be convenient sometimes if you could restrict the shift-enter renaming to the rest of the file or to a block, but I do not know if that is possible. I end up using the control-F find function and clicking on Replace multiple times until I reach the end of the section.

OK< Thanks.

Yes that is what I mean. It ends up not being too much of a hassle to manually replace the variables but I was just curious if there existed a method to do as you described. Thanks.

I think this would still be a really useful feature to have.

Yes, This would be a great feature!

I use a tool called UltraEdit. It has that capability. In the find/replace tab there is a checkbox for "replace all is from top of file".

Simply uncheck this box and "replace all" operates from the cursor to the end of file.

UltraEdit can also restrict edits to a selected column or range of columns of data. Great feature.
