What is the difference between the remap, noremap, nnoremap and vnoremap mapping commands in Vim?
811
On vim , command-mode keys can be mapped through the ex command :map <key> <macro> and insert-mode keys can be mapped through :map! <key> <macro> . After mapped, the commands to remove the mapping from the command-mode keys and insert-mode keys are unmap <key> and unmap!
The <CR> in vim mappings is the carriage return usually the Enter on your keyboard.
<silent> tells vim to show no message when this key sequence is used. <leader> means the key sequence starts with the character assigned to variable mapleader -- a backslash, if no let mapleader = statement has executed yet at the point nmap executes.
remap is an option that makes mappings work recursively. By default it is on and I'd recommend you leave it that way. The rest are mapping commands, described below:
:map and :noremap are recursive and non-recursive versions of the various mapping commands. For example, if we run:
:map j gg (moves cursor to first line) :map Q j (moves cursor to first line) :noremap W j (moves cursor down one line) Then:
j will be mapped to gg.Q will also be mapped to gg, because j will be expanded for the recursive mapping.W will be mapped to j (and not to gg) because j will not be expanded for the non-recursive mapping.Now remember that Vim is a modal editor. It has a normal mode, visual mode and other modes.
For each of these sets of mappings, there is a mapping that works in normal, visual, select and operator modes (:map and :noremap), one that works in normal mode (:nmap and :nnoremap), one in visual mode (:vmap and :vnoremap) and so on.
