title: What is the IntelliJ shortcuts used with mouse click?
body: <p>I am new in IntelliJ (use v2021.1) and just learn several shortcuts and use them. However, I realized some shortcuts that can be used with mouse click as shown below:</p>
  <p>Ctrl + Click</p>
  <p>Alt + Click</p>
  <p>I think they have multiple purposes e.g. go to definition, find usages. But I want to learn what their usages exactly?</p>
  <p>And is there similar useful shortcuts that can be used with mouse click in IntelliJ IDEA?</p>
