Try to isolate the problem. First, while running vim, try something like
:nmap , :echo "hello"<CR>
and then type ,. Assuming that works, try the key combination you actually want, instead of ,. (When you write [CTRL]+[\]+s
, you are using the CTRL and \ keys at the same time, right?) If that works, then try the actual cscope command from the tutorial.
Next, try adding a simple nmap
command to your vimrc file. Does that work?
You should be able to load the script with
:source path/to/cscope_maps.vim
If that works, but simply dropping the file in your plugin directory did not, try
:set runtimepath?
to see which directories are being searched for plugins, and read
:help load-plugins
(Step 4 under :help startup
) for other reasons they might not be loaded.
