    <p><code>remap</code> is an <strong>option</strong> that makes mappings work recursively. By default it is on and I'd recommend you leave it that way. The rest are <strong>mapping commands</strong>, described below:</p> <p><code>:map</code> and <code>:noremap</code> are <strong>recursive</strong> and <strong>non-recursive</strong> versions of the various mapping commands. What that means is that if you do:</p> <pre><code>:map j gg :map Q j :noremap W j </code></pre> <p><code>j</code> will be mapped to <code>gg</code>. <code>Q</code> will <em>also</em> be mapped to <code>gg</code>, because <code>j</code> will be expanded for the recursive mapping. <code>W</code> will be mapped to <code>j</code> (and not to <code>gg</code>) because <code>j</code> will not be expanded for the non-recursive mapping.</p> <p>Now remember that Vim is a <strong>modal editor</strong>. It has a <strong>normal</strong> mode, <strong>visual</strong> mode and other modes.</p> <p>For each of these sets of mappings, there is a <a href="http://vim.wikia.com/wiki/Mapping_keys_in_Vim_-_Tutorial_%28Part_1%29#Creating_keymaps" rel="noreferrer">mapping</a> that works in normal, visual, select and operator modes (<code>:map</code> and <code>:noremap</code>), one that works in normal mode (<code>:nmap</code> and <code>:nnoremap</code>), one in visual mode (<code>:vmap</code> and <code>:vnoremap</code>) and so on.</p> <p>For more guidance on this, see:</p> <pre><code>:help :map :help :noremap :help recursive_mapping :help :map-modes </code></pre>

    1. COThanks for your answer! Also, when is recursive used, and when is non-recursive used?

    2. CO@Chetan: It depends what you want to achieve. I tend to use non-recursive more often, but if you've defined a relatively complicated mapping using non-recursive and what another mapping that does everything the first mapping does and more, it can be easier to use a recursive mapping that includes the original one rather than retyping the whole of the non-recursive one again (particularly if you then need to tweak the original one).

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
