I try map my Capslock key to ctrl key while using vim and I search for this on stackoverflow and I found

```Linux? With X, use xmodmap to alter the key mapping, e.g.

xmodmap -e 'clear Lock' -e 'keycode 0x42 = Escape'
Will map Esc to the CapsLock key. Google for more examples.```

following command it will map Esc key to CapsLock key but when I run this command my CapsLock key did stop working and nor my esc key map to CapsLock key. How do I get back my Capslock key default working state, I mean I don't want to map Capslock key to ctrl key?
