<C-r> <C-Q>

[imhgy]

Hi, I want to remap the <C-r> and <C-q> for undo and block select with <C-S-z> and vv in normal mode，

I tried:

nmap vv <C-q>
nmap <C-S-z> <C-r> 
`` and
map vv <C-q>
map <C-S-z> <C-r> 

Unfortunately, they didn't work, Are there any suggestions?

i am trying

noremap <C-s> 9<C-e> 
noremap <C-w> 9<C-y> 

or

noremap <C-s> 15<C-d> 
noremap <C-w> 15<C-u> 

to scroll in the file, but it doesn't work, i works when done manually, i guess there is a problem with mapping to Control key or something
