Anyone on a Unix system that uses readline (most) should be able to use these handy little dance moves.
- Ctrl a Moves the cursor to the start of the line
- Ctrl e Moves the cursor to the end of the line
- Ctrl r Context search of your history, hit ctrl r and start typing. Hit ctrl r again to scroll
- Tab Seriously, you don’t know about tab completion? How do you dress yourself every day?
Lots more of that here, but those are my most frequent.
