    <p><strong>EDIT 3:</strong> I've gotten this working by ignoring the advice given below and listening on the window, but only when an <code>input</code>, <code>text</code> field, or <code>textarea</code> is not focused. I'm not sure if this is the best way to be handling this issue, though.</p> <p><a href="http://jsfiddle.net/gXPES/5/" rel="nofollow">http://jsfiddle.net/gXPES/5/</a></p> <hr> <p><strong>EDIT 2:</strong> I've tried addressing the <code>keydown</code> issue by applying <code>focus</code> and <code>blur</code> handlers to <code>input</code>s. Then I only listen for events when <code>var focus_on_input == true</code>. But it seems that not all is well. This is preventing some behaviors, but causing other, more bizarre behavior. For example, when I <kbd>tab</kbd> out of the input field, pressing <kbd>J</kbd> and <kbd>K</kbd> will jump to the top or bottom of the list. If I <code>click</code> elsewhere and shift focus, this issue is fixed. Any thoughts?</p> <hr> <p><strong>EDIT:</strong> Thanks to answerer help, I've limited the selectors when listening for <code>keydown</code> so that I can still type characters elsewhere, but I'm running into a new issue. When I press <kbd>J</kbd> or <kbd>K</kbd> the arrow nav jumps to the top or bottom of the task list. And when I press <kbd>C</kbd> or <kbd>#</kbd> it will notify me that no tasks are selected. <kbd>X</kbd> functions as it should and does not select a task.</p> <hr> <p>Hosting <a href="http://jsfiddle.net/gXPES/" rel="nofollow">this code on JSFiddle</a> since there's no possible way to comment on it in its entirety here. I've posted all my JS, CSS, and HTML used for the interface itself.</p> <p>I'm designing a Gmail-inspired UI for task management using jQuery on the front-end (and PHP on the back-end, though it's largely irrelevant to this).</p> <p>I'm still relatively new to jQuery development and so I realize <strong>I'm doing a number of things wrong</strong>. Until now, I simply haven't known <strong>what exactly</strong> I'm doing wrong nor <strong>how to fix it</strong>. I was hoping some more learned souls might help me (and others, hopefully) figure out how to refactor jQuery code for a larger-sized application.</p> <p>To start, here are a number of things I would like to know how to do better:</p> <ol> <li><p>Call this code only when the task interface is active.</p></li> <li><p>Improve the listening for the <code>keydown</code> event. Currently I listen for <kbd>J</kbd>, <kbd>K</kbd>, <kbd>X</kbd>, <kbd>Shift+3</kbd>, and <kbd>C</kbd>. I will also be listening on <kbd>E</kbd> for task editing, but haven't yet implemented edits. <strong>The problem with the listeners</strong> is related to my first concern, which <strong>is that they are always on</strong>. This means that pressing <kbd>J</kbd> while in a <code>&lt;textarea&gt;</code>, for example, will not result in the default behavior.</p></li> <li><p>Use less HTML in my code.</p></li> <li><p>Make my code generally more DRY.</p></li> </ol> <p>Any thoughts, no matter how critical, are more than welcome. Again, I realize I am not following best practices here, but that's because I'm dumb to them. I want to learn, and hope to use this opportunity to do so.</p> <p>Cheers!</p>

    1. COProbably not the criticism you're looking for, but how about using <space> for select? I believe it will check/uncheck boxes in other UIs, so that's kind of what I would expect. I also don't know why gmail uses j/k instead of W/S...gamers would expect that..but whatever :p **Edit:** Nvm..space scrolls the page in FF.

    3. CO@Mark, I could certainly use both <kbd>space</kb> and <kbd>X</kbd>. I'm personally a Gmail power user so that's why I chose the chars I did. What other UIs do you know of that use <kbd>space</kbd>? **Edit:** Gotcha on FF. Same with Chrome. That may be a browser-wide standard.

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
