Should "caps" be changed to "caps-lock"?

In the syn keycodes, we have...

pause-break
num-lock,
scroll-lock,
page-up,
page-down,

"caps" seems not to fit the usual naming convention.

Inspect the syn keycode definitions and search for references to the "caps" name. Confirm whether the naming should match the surrounding lock-key conventions, update the affected references consistently, and verify that existing keycode behavior remains unchanged.
