Cannot highlight all occurrences of a selected word in Eclipse

Question

I tried using the Toggle mark occurrences (Alt + Shift + O) button and also in Preferences -> General -> Editors -> Text Editor -> Annotations

Answer 1

Preferences --> Java --> Editor --> Mark Occurrences

Answer 2

Find the Preferences under Window,

In General > Editors > Text Editors > Annotations(1)

(5) is to select the color and press apply.

Answer 3

If you go into the window-prefrences, select the language you want/are working with. Select the editor under this specific language and then there is a mark occurrences there that has some options. Where it says keep marks when the selection changes, for me this was checked. When I unchecked it the system started highlighting correctly.

Answer 4

For folks who are using a dark background with light font colors, you may want to check out the highlight color in Preferences -> General -> Editors -> Text Editor -> Annotations. Mine was defaulted to black, which does not stand out on a black background.

Answer 5

For Eclipse Mars:

Window --> Preferences --> Check (Mark occurrences of the selected element in the current file.)

As shown if figure:

Answer 6

1. Click the word and hold until a popup appears as shown in the figure.
2. On the popup, there is a little right arrow, after clicking it, a new icon shows up.
3. Click that link to open preferences.
4. Once in preferences, select C/C++ Occurrences (it will be language specific) and select Include in next/previous navigation with Text as Highlighted.

This should enable the feature of highlighting all occurences of the selected word in the opened file.
