Instead of Search & Replace, this extension is to allow you to create similar lines of code that vary. Provide a list of comma seperated values, and a line of code with %%% wherever you want the value inserted, and for each of the list items, it will generate a corresponding line of code.
Quick and easy generation of lines of code to eliminate the need for manual copying and pasting.
Click the CodeGen button that will be installed on the status bar. This should open a panel which lets you enter your values (copy & paste them in) and hit Generate. Then simply copy and paste the resulting lines of code into your project.
