I have the following line in a file I\'m editing in VSCode:
...............111.........111.............111..
I want to replace all .
From the VSCode devs:
We used to enable find in selection automatically when opening the find widget with a selection, but it was too easy to trigger accidentally and produced a lot of complaints. You probably want to set "editor.find.autoFindInSelection": true which will make it work the way you expect.
The VSCode GitHub issue has more details if anyone is interested.
EDIT: The autoFindInSelection option is available starting from VSCode 1.13. That version is currently in development (as of 6/7/2017), so this fix won't work until the new version is released.
