|

|
|
Is being familiar to Vim a path to productivity?
|
||
|
|
No.
|
||
|
|
But being good at it can make for a difference in the day-to-day life of a sysadmin for there are advanced capabilities of this editor.

</p><h1 id="the-keybindings-of-vim">The keybindings of Vim</h1><p>One of the things that make Vim popular is the keybindings.
|

</p><table><thead><tr><th>Keybinding</th><th>Description</th></tr></thead><tbody><tr><td><code class="inline-verbatim">[m</code></td><td>Go to the previous method.</td></tr><tr><td><code class="inline-verbatim">g~w</code></td><td>Toggle letter casing.</td></tr><tr><td><code class="inline-verbatim">2guW</code></td><td>Convert two words into lowercase.</td></tr><tr><td><code class="inline-verbatim">10d)</code></td><td>Delete 10 sentences.</td></tr><tr><td><code class="inline-verbatim">39zz</code></td><td>Place the cursor in the middle in line 39.</td></tr><tr><td><code class="inline-verbatim">3d10w</code></td><td>Delete 10 words and repeat 3 times.</td></tr></tbody></table><p>Most of the time, Vim keybindings is made of mainly two things:
|
||
|
|
</p><ul><li><p><strong>The operators denoting an action.</strong></p></li><li><p><strong>The motions describing the scope of the action.</strong></p></li></ul><p>There's a certain pattern to it when you use it, too.

</code></pre><h1 id="tips-and-tricks">Tips and tricks</h1><ul><li><p><code class="inline-verbatim">:h</code> is the help system of Vim.
|
||
|
|
It contains all of the documentation of the editor and the installed plugins.
|
||
|

I recommend to start with the default help page (e.g., <code class="inline-verbatim">:h</code>).
|

|

</p><ul><li><p>You can get the meaning of the keybinding with the help section — e.g., <code class="inline-code">:h gg</code>, <code class="inline-code">:h G</code>.
