There are two screencasts on Navigation which you may also find useful:
Navigating Forward & Backward
Move forward and backward between your locations in the code
Navigate to Implementation
Go to one or more implementations across your code base
Find Usages
Use Find Usages to search for references in your code base
Navigate to Test
Go to your matching test class
Recent Files
Navigate to any of the files that you recently had open
Recent Locations
Quickly navigate around your recent locations in your code base
F2
Quickly move to the next (or previous) error or warning in the file.
While you're coding, you may want to jump to the next error or warning (F2) or the last one (Shift+F2). This way, you can quickly hop to the next thing that needs fixing or addressing without having to move your hand to the mouse.
Combine this with ⌥⏎ (macOS), or Alt+Enter (Windows/Linux) to quickly see the suggested solution to the problem and apply a fix. This will show a list of suggested solutions, as we saw in the tip about Alt+Enter, and we can pick the solution that suits us best.
If you're confident IntelliJ IDEA has the correct fix for the problem, you can skip the step of listing the solutions. Press F2 to navigate to the problem, then press ⌥⇧⏎ (macOS), or Shift+Alt+Enter (Windows/Linux), to accept IntelliJ IDEA's suggested fix.
