I have two mappings like this:
nnoremap <s-c> zz inoremap <s-c> <esc>zza
As you can see, I just want to use
<s-c> to redraw the current line to the middle of the windows in both normal and insert mode. But, surprisingly, after that mapping, I cannot enter the uppercase
C in insert mode any more. Why?
Is it because that the uppercase
C by default mapped (recursively) to the
<s-c>? (I guess this because in many keyboard pressing
<s-c>has the same effect as pressing a uppercase C, that is, you get a
C in your buffer.)
If so, how can I unmap it?
