Eclipse highlights the same variable selected

Problem Description:

Use shortcut keys or other reasons in eclipse, accidentally pressing the wrong, so that the variable highlighting is gone.

1. How to solve the user:

Select:windows-> Preferences->java->editor->mark occurences

Select the top check box, and the following is a lot.

The local variables is the highlight of the variable.



2. There are also simpler ways to do this:

Online search, originally toggle Mark occurrences (Alt + Shift + 0)
This button does not press the icon in the shape of the small yellow color pen in the toolbar.

3. Change its color:

Select:windows-> Preferences->java->editor->mark occurences-> The first line has a "Annotations" click to enter, display the list, find occurrence annotation to the right, select color.
