When I mark a word (of any kind) I would like all occurrences (in that particular file) of that word to be highlighted in the scrollbar on the right hand side.
This was a feature in VS2015 and VS2013. I cannot imagine that they removed it, I just don't know how to switch it on. None of the apparent possibilities in Tools -> Options (image) helps me.
Ps. I am using Visual Studio 17 Professional. Thank you.
This was a feature in VS15 and VS13.
Actually it was not.
It is a feature of the Productivity Power Tools extension. That extension is now just an installer for separate single feature extensions. I think you'll be wanting Match Margin.
For Visual Studio 2022 Match Margin is also available.
There's another extension which does exactly this, with options to customize colors and more. it called Word Highlight With Margin.

Right now, the only way I know (without installing new extensions) is to select (double click) the word and hit ctrl-f (find). Scroll map should highlight all occurences (mine are orange)
