Is there a way to highlight all instances of the variable under the cursor?

Many code editors (such as MATLAB’s) can highlight all occurrences of the variable which is under the cursor. Is this possible in Mathematica?

For example I create a variable, then I use it many times, and when I place the cursor in that variable, then every place where I use it, it highlights. So, you can see the variable where I use it in all code.
