Why Keyboard Shortcuts Are Worth Learning
Every time you move your hand from the keyboard to the mouse, you lose a small amount of time. Multiply that across hundreds of actions per day and it adds up to a meaningful chunk of your working hours. Learning keyboard shortcuts is one of the highest-return-on-investment productivity habits you can build — a few minutes of practice per day quickly becomes second nature.
This guide covers the shortcuts that provide the most value across everyday computing tasks.

| Redo | Ctrl + Y | Cmd + Shift + Z |
| Select All | Ctrl + A | Cmd + A |

Text Editing Power Moves

How to Build the Habit
Don't try to memorise all of these at once. Pick three shortcuts that apply to tasks you do every day and use only those for a week. Once they're automatic, add three more. Within a month, you'll have a solid repertoire of shortcuts that feel completely natural.
A useful trick: put a sticky note on your monitor with your "current" shortcuts to remind yourself to use them instead of reaching for the mouse.
