Quick Definition Action
Quick definition is similar to its counterpart from IntelliJ IDEA. Point a cursor onto a node and press ctrl-shift-i. You will see a popup with the definition of the node. You might navigate, select and perform find action in the popup. Thus, you don't need to open a new tab to simply get a glance at the node.
Quick definition works in a completion menu as well. If you are not familiar with the node meaning you might press ctrl-shift-i and see its definition alongside the completion menu. As you navigate through the completion menu, the contents of the popup will change accordingly.
