I cannot enter command mode by typing :.
What's more , whatever key I press, Vim will enter insert mode and type the word I've just typed. i.e. I type j, and the cursor doesn't move downwards but Vim enters insert mode and types the letter j on the screen, which is very weird.
I reinstalled Vim and it made no difference
Now as I cannot enter command mode, I cannot type :wq to save any change to vimrc file.
If the is problem caused by the wrong setting in vimrc, I have no idea about how to fix it. If not, what's the cause of the issue?

If it's a problem with my .vimrc, how can I edit the file and save the edit in these circumstances?
