As a programmer, your keyboard is your main input method. As with pretty much anything in your computer, it is configurable (and worth configuring).
The most basic change is to remap keys. This usually involves some software that is listening and, whenever a certain key is pressed, it intercepts that event and replaces it with another event corresponding to a different key. Some examples:
- Remap Caps Lock to Ctrl or Escape. We (the instructors) highly encourage this setting since Caps Lock has a very convenient location but is rarely used.
- Remapping PrtSc to Play/Pause music. Most OSes have a play/pause key.
- Swapping Ctrl and the Meta (Windows or Command) key.
