Vim mappings - to map keys on your keyboard to specific Vim actions
Basics
Open Vim and type
:map <space> diw
The above mapping maps space key to diw (delete word) in Normal Mode.
:map <c-d> dd
Press Ctrl+d and the whole line gets deleted.
You get the idea.
To remove the above mappings, type
:unmap <space>
:unmap <c-d>
But what if we map x to diw. As we know, pressing x in Normal Mode deletes the character under the cursor.
:map x diw
Now pressing x will delete a word, deviating from its default action.
Btw, these mapping also work in Visual Mode. What if we want to map keys to work only in Normal Mode? In that case, we have to be more specific. Read on.
Modal Mapping
nmap- Normal Mode mappingvmap- Visual Mode mappingimap- Insert Mode mapping
:nmap - dd
Pressing - will delete the whole line only in Normal Mode.
:vmap - U
Pressing - will change the selected text to uppercase only in Visual Mode.
Insert Mode mapping is a bit different. Let’s map - to delete a word in Insert Mode.
:imap - diw
The above mapping won’t work. It will insert the text "diw".
Solve this using the following mapping
:imap - <esc>diwi
<esc>- switch to Normal Modediw- delete wordi- switch to Insert Mode
You can remove the above mappings using
:nunmap:vunmap:iunmap
