Eclipse has the Mark Occurrences feature where it highlights all occurrences of a selected variable/method. Is there a way to navigate to next or previous marked occurrence?
If you are looking to navigate through variables / methods defined in the same class, a quicker way to do this would be to select ( highlight ) the variable / method name you want to navigate to and use Alt + Shift + R to get into the refactoring mode and then use Tab or Shift + Tab.
Tab - takes you to the next occurrence
Shift + Tab - takes you to the previous occurrence
This way will save you from reaching mere text matches ( including those in comments ), as how Ctrl + K behaves. So you are taken through only "valid" occurrences.
