Caps Lock is a toggle key because it:
- Switches between uppercase and lowercase typing
- Remains in the selected state until pressed again
- Does not require holding down the key
Toggle keys are keys that switch between two states, typically indicated by a light or changed behavior.
The other options:
- Esc (Escape) is a command key that cancels or exits operations.
- Shift is a modifier key that changes the behavior of other keys.
- Spacebar is a non-modifier key that inserts spaces.
Other examples of toggle keys include:
- Num Lock
- Scroll Lock
- Insert
These keys also switch between two states when pressed.
