Hi. I'm using AceJump 3.8.20 and IntelliJ IDEA 2024.2.4 (Ultimate Edition).
When I cycle the mode with my shortcut (control + ;), it shows four colors in order:

I wonder what is the 4th mode (green in picture) because it seems the same with the 3rd - last position of the word.
I checked the keymap settings but it just said Activate | Cycle AceJump Mode and there's no description in README so I've lost the way.
