At declaration: Jumps to call-site
What it does
Main menu > Navigate > Implementation(s)
Useful for jumping to the implementation from the interface method (trait)
Why should you use it

At declaration: Jumps implementation
What it does

Why should you use it
Opens dialog for git stash/unstash
What it does
Main menu > VCS > Git > Show History for Selection
Incredibly useful for understanding why something was changed and who did it
Why should you use it
Shows all commits that touched the selected code
