IEdit for Visual Studio Code
IEdit for Visual Studio Code is an extension that will monitor changes while you edit your files and automatically find similar changes nearby, allowing you to change all of them with a single click, or one at a time. So now you don't have to make the same change over and over again.
If you change "foo" to "bar", it will look for other instances of "foo" nearby below your change and prompt you for each one. Or you can choose to change all of them at once.
It will also attempt to adjust the case for the replacement string to match what is being replaced (see above).
Here's an animation showing how after making a change, it will show suggestions which you can then accept by clicking the link or using the Ctrl+\ and Ctrl+Shift+\ shortcuts (Cmd+\ and Cmd+Shift+\ for Mac):
