vim Configuring Vim Mappings
Example
- Don't put comments after mappings, it will break things.
- Use
:map <F6>to see what is mapped to<F6>and in which mode. - Use
:verbose map <F6>to also see where it was last mapped. :mapand:map!are too generic. Use:n[nore]mapfor normal mode mappings,:i[nore]mapfor insert mode,:x[nore]mapfor visual mode, etc.
Recursive mappings
Use recursive mappings only if you intend to use other mappings in your mappings:
nnoremap b B
nmap <key> db
In this example, b is made to work like B in normal mode. Since we use b in a recursive mapping, pressing <key> will work like dB, not like db.
Non-recursive mappings
Use non-recursive mappings only if you intend to use default commands in your mappings, which is almost always what you want:
nnoremap <key> db
In this example, we use b in a non-recursive mapping so pressing key will always work like db, whether we remapped b or not.
Executing a command from a mapping
nnoremap <key> :MyCommand<CR>
Executing multiple commands from a mapping
nnoremap <key> :MyCommand <bar> MyOtherCommand <bar> SomeCommand<CR>
Calling a function from a mapping
nnoremap <key> :call SomeFunction()<CR>
Mapping a <Plug>mapping
map <key> <Plug>name_of_mapping
See :help map-commands, :help key-notation and :help <plug>.
