Highlighting all occurrences of a word that was selected by a double click was provided by solving bug #41470. The lines of the occurrences in the visible region are additionally marked in the left margin. However there is no scoped highlighting or a visualization of all occurrences in the text in the vertical scrollbar. I am changing the title of this report accordingly.

It would be very beneficial if all instances of a selected variable could be highlighted in the editor. I've found this a very useful feature I rely on in the Matlab and Notepad++ editors. It helps to know where else in the code a variable is used (or not used due to mis-spelling). Notepad++ highlights all variables of the same name, whereas Matlab does scoped highlighting. I've found both to be useful in different ways, either to limit highlighting to a given code scope, or to see all places a phrase or variable by the same name is used in any scope or in comments. I'd be happy if either method were implemented (and happiest if both were implemetned with an option to toggle between methods). 

Another very useful extension to variable highlighting is if a colored marker is placed by the scrollbar to show where instances occur in the whole document, not just where they are visible in the current view. Matlab does this and I have an addon in Notepad++ to do this (and used to have an addon in firefox that did the same on ctl-f on searches).
