Recently, while working on a project, I saw experts using shortcuts with incredible efficiency. Their proficiency was awe-inspiring, highlighting the gap between us. While you’re still slowly moving your mouse, the expert might have already switched between numerous files and executed several actions efficiently. This gap in efficiency multiplies over time. Seeing this gap has motivated me to start mastering various common shortcuts. Here, I record them for my reference and perhaps to help others.

Disclaimer
- Since I am a Mac user and a Developer, the software and skills covered here are focused accordingly.
- Some shortcuts are marked with * indicating that they are custom settings, not software defaults, and are for reference only.
- The operational techniques must also be continually adjusted and enriched in practice, so
this document will be continuously updated.
- I set the F media keys as function keys, so low-frequency media key operations require Fn, but other high-frequency operations become simpler.

Conclusion
Muscle Memory - the human muscles have a memory effect. After repeating the same action multiple times, the muscles will form a conditioned reflex. The speed at which the human body’s muscles acquire memory is very slow, but once acquired, the speed of forgetting is also very slow. So, practice repeatedly, remember repeatedly, and benefit for life.
