如果我cat /usr/share/X11/xkb/rules/evdev.lst | grep caps:在终端输入
caps:internal Caps Lock uses internal capitalization; Shift "pauses" Caps Lock
caps:internal_nocancel Caps Lock uses internal capitalization; Shift does not affect Caps Lock
caps:shift Caps Lock acts as Shift with locking; Shift "pauses" Caps Lock
caps:shift_nocancel Caps Lock acts as Shift with locking; Shift does not affect Caps Lock
caps:capslock Caps Lock toggles normal capitalization of alphabetic characters
caps:shiftlock Caps Lock toggles Shift Lock (affects all keys)
caps:swapescape Swap Esc and Caps Lock
caps:escape Make Caps Lock an additional Esc
caps:escape_shifted_capslock Make Caps Lock an additional Esc, but Shift + Caps Lock is the regular Caps Lock
caps:backspace Make Caps Lock an additional Backspace
caps:super Make Caps Lock an additional Super
caps:hyper Make Caps Lock an additional Hyper
caps:menu Make Caps Lock an additional Menu key
caps:numlock Make Caps Lock an additional Num Lock
caps:ctrl_modifier Make Caps Lock an additional Ctrl
caps:none Caps Lock is disabled
我无法区分“Caps Lock 使用内部大写”、“Caps Lock 充当带锁定的 Shift”（与 Shift Lock 不同）和“Caps Lock 切换正常大写”。
