It’s a sign you really know your way around Photoshop when you’ve mastered the keyboard shortcuts for moving around the Layers palette. Here are a couple reminders:
Select Layers: Bracket keys [ or ] while holding Option (PC: ALT).
Move Layers: Bracket keys [ or ] while holding Command (PC: CTRL).
Adobe has a full list on their help page: Keys for using the Layers panel.
