I used to be able to use alt-left click for jumping to a method or class definition. This week it just stopped working. Sometimes it was not great and I had to reopen projects (Laravel) but now it has stopped working entirely.
Strangely though, while holding down alt and hovering the mouse over the methods or classes the words still underline and the cursor turns into the hand but now when I click them nothing happens.
Any help would be much appreciated. I am lost without this.
