With supplementary searching, I've found that someone asked nearly the same <a href="https://stackoverflow.com/questions/117150/can-i-re-map-commands-in-vim">question</a> as I.

<pre><code>:command &lt;AliasName&gt; &lt;string of command to be aliased&gt;

will do the trick.

Please be aware that, as <a href="https://stackoverflow.com/users/182327/richo">Richo</a> points out, the user command must begin with a capital letter.

To leave completion untouched, try using
<pre><code>cnoreabbrev W w
</code></pre>
It will replace <code>W</code> in command line with <code>w</code>, but only if it is neither followed nor preceded by word character, so <code>:W&lt;CR&gt;</code> will be replaced with <code>:w&lt;CR&gt;</code>, but <code>:Write</code> won’t. (Note that this affects any commands that match, including ones that you might not expect. For example, the command <code>:saveas W Z</code> will be replaced by <code>:saveas w Z</code>, so be careful with this.)
<h3>Update</h3>
Here is how I would write it now:
<pre><code>cnoreabbrev &lt;expr&gt; W ((getcmdtype() is# ':' &amp;&amp; getcmdline() is# 'W')?('w'):('W'))
</code></pre>
As a function:
<pre><code>fun! SetupCommandAlias(from, to)
 exec 'cnoreabbrev &lt;expr&gt; '.a:from
 \ .' ((getcmdtype() is# &quot;:&quot; &amp;&amp; getcmdline() is# &quot;'.a:from.'&quot;)'
 \ .'? (&quot;'.a:to.'&quot;) : (&quot;'.a:from.'&quot;))'
endfun
call SetupCommandAlias(&quot;W&quot;,&quot;w&quot;)
</code></pre>
This checks that the command type is <code>:</code> and the command is <code>W</code>, so it’s safer than just <code>cnoreabbrev W w</code>.

The best solution involves <a href="https://github.com/trapd00r/configs/blob/master/vim/nancy/000-functions.vim#L100-L106" rel="nofollow noreferrer">writing a custom function</a> for handling abbreviations that only take place in the beginning of the command bar.
For this, add the following your vimrc file or anywhere else.
<pre><code>&quot; cabs - less stupidity {{{
fu! Single_quote(str)
 return &quot;'&quot; . substitute(copy(a:str), &quot;'&quot;, &quot;''&quot;, 'g') . &quot;'&quot;
endfu
fu! Cabbrev(key, value)
 exe printf('cabbrev &lt;expr&gt; %s (getcmdtype() == &quot;:&quot; &amp;&amp; getcmdpos() &lt;= %d) ? %s : %s',
 \ a:key, 1+len(a:key), Single_quote(a:value), Single_quote(a:key))
endfu
&quot;}}}
</code></pre>
 
<pre><code>&quot; use this custom function for cabbrevations. This makes sure that they only
&quot; apply in the beginning of a command. Else we might end up with stuff like
&quot; :%s/\vfoo/\v/\vbar/
&quot; if we happen to move backwards in the pattern.

&quot; For example:
call Cabbrev('W', 'w')

A few <a href="https://github.com/trapd00r/configs/blob/master/vim/02-mappings.vim#L165" rel="nofollow noreferrer">useful abbreviations from the source material</a> where I found this stuff:

call Cabbrev('?', '?\v')

call Cabbrev('s#', 's#\v')

call Cabbrev('s@', 's@\v')
call Cabbrev('%s@', '%s@\v')

call Cabbrev('s!', 's!\v')

blocks|key|3018464|text|我认为@ZyX的答案很好，但如果你使用的是较新版本的neovim+(0.5%2B)，你可能想用lua来定义函数。这是你可以做到的一种方法：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3018465|function+_G.abbreviate_or_noop(input,+output)

I think @ZyX's answer is great, but if you're using a newer version of neovim (0.5+), you might want to define the function using lua instead. Here's one way you could do it:
<pre><code>function _G.abbreviate_or_noop(input, output)
 local cmdtype = vim.fn.getcmdtype()
 local cmdline = vim.fn.getcmdline()

 if (cmdtype == &quot;:&quot; and cmdline == input) then 
 return output
 else
 return input
 end
end

function SetupCommandAlias(input, output)
 vim.api.nvim_command(&quot;cabbrev &lt;expr&gt; &quot; .. input .. &quot; &quot; .. &quot;v:lua.abbreviate_or_noop('&quot; .. input .. &quot;', '&quot; .. output .. &quot;')&quot;)
end
</code></pre>
Then, you'd drop the <code>call</code> from <code>call SetupCommandAlias(&quot;pg&quot;, &quot;postgres://&quot;)</code> and just use the function like this: <code>SetupCommandAlias(&quot;pg&quot;, &quot;postgres://&quot;)</code>.
n.b. If using it from a <code>.vim</code> file instead of a <code>.lua</code> file, you'd need to prefix the function call with <code>lua</code>, i.e. <code>lua SetupCommandAlias(&quot;pg&quot;, &quot;postgres://&quot;)</code>.

Vim is my preferred text editor when I program, and thus I always run into a particularly annoying issue.
Frequently, when I quickly need to save the buffer and continue on to some other miscellaneous task, I do the typical
<pre><code>:w
</code></pre>
However, I always — what seems to be like more than 50% of the time — manage to capitalize that <code>:w</code>. Naturally, Vim yells at me because <code>W</code> is an invalid command:
<pre><code>E492: Not an editor command: W
</code></pre>
My question is how can one alias colon-commands in Vim. Particularly, could you exemplify how to alias <code>W</code> to <code>w</code>.
I am aware of the process to map keys to certain commands, but that is not what I’m looking for.
