Parse words on hover/on holding hotkey

[RomanNur]

Currently the only working way for me to load tooltips for words is either:

1. click on extension -> click "Parse {tab name}"
2. select text -> right click->click "Parse {selected text} with jpdb"

In settings I have this, but even when I'm holding shift, or "select text + holding shift" - popup with explanation doesnt show up, no requests are sent to jpdb. What am I doing wrong, how can I debug this? I also tried different keybind, but it didnt help.
