Most Impactful for Your Workflow

Based on working with ML/Stats research across different RunPod instances:

1. Ctrl+R (terminal) - Search bash history for your infrastructure commands (sync_to_s3, ghcreate, etc.)
2. Ctrl+P (Cursor) - Lightning-fast file switching across projects
3. Ctrl+Shift+F (Cursor) - Find code patterns across your entire workspace
4. Ctrl+K (Cursor AI) - Inline AI refactoring for quick code improvements
5. Ctrl+D (Cursor) - Multi-select for renaming variables without find-replace dialogs

Pro Tips

• Create bash aliases for your most-used commands in /workspace/.bashrc:

  alias s3p='sync_to_s3'  # Quick sync push
  alias s3u='sync_from_s3'  # Quick sync pull

• Use Ctrl+R like a pro: Type partial command, hit Ctrl+R repeatedly to cycle through matches

• Multi-cursor power: Select a variable with Ctrl+D, keep pressing to select more occurrences, type once to change all
