There are two keyboard shortcuts that I want to teach you today: Shift+Shift to open up Search Everywhere, and Alt+Enter.
Search Everywhere gets you anywhere in your project. You can start typing and it'll search for classes, files, symbols, and even for actions across the IDE.
Rider is looking at your code and scanning it, and tries to find and suggest fixes for issues in your code. Anywhere you place the caret, you can use With Alt+Enter to show a menu of context actions and available quick-fixes.
