Eclipse does not highlight matching variables

Question

Eclipse does not highlight matching variables for me:

I\'ve already tr

Answer 1

Using Alt + Shift + o It works for me!

Answer 2

I had this issue with Eclipse Mars for PHP developers, 64 bit edition for Windows. I now discovered that highlighting works out-of-the-box with the 32 bit version. Even with a fresh download of the equivalent 64 bit build, highlighting does not work. So I will switch back to 32 bit (this is actually not the first problem I observe with Eclipse 64 bit).

Edit:

I thought this was the solution, so I installed the 32 bit version in C:\Program Files (x86) and set a shortcut in the "Start" menu. When I started Eclipse from there, highlighting again ceased to work. I now got it working again by deleting the .metadata directory in the workspace (i.e. resetting the workspace settings) and re-importing the projects.

Answer 3

This is what worked for me (credit to YardenST from another thread): Instead of double clicking file when opening, right click on file -> Open with -> Java editor

Answer 4

The only that worked for me was:

Java > Editor > Mark Occurrences:
Check "Mark occurrences of te selected element in the current file."
... and maybe all the ones below.

Answer 5

For PHP you can set

window > preferences > PHP > editor > mark occurrences 

Please check first checkbox (Mark occurrences of selected element in the current file)

---

And also check

Preferences > General > Editors > Text Editors > Annotations

'Occurrences' and 'Write Occurrences' with different style and color
