    <p>I'm new to AS3 and although I was looking for a solution to my problem truly long time, I was not successful. I have an animated presentation and I just want to make navigation through that by arrows. Everything is on the main timeline. In the first frame I made this code </p> <pre><code>var zpet: Number; if (currentFrame == 1) { zpet = 1; } stage.addEventListener(KeyboardEvent.KEY_DOWN, posun); function posun(event: KeyboardEvent): void { if (event.keyCode == 37) { addEventListener(Event.ENTER_FRAME, playReverse); function playReverse(event: Event): void { if (currentFrame == zpet) { stopPlayReverse(); } else { prevFrame(); } } function stopPlayReverse(): void { if (hasEventListener(Event.ENTER_FRAME)) { removeEventListener(Event.ENTER_FRAME, playReverse); } } } else if (event.keyCode == 39) { if (currentFrame &lt; totalFrames - 1) { play(); } else { stop(); } } } stop(); </code></pre> <p>Moving forward works perfect as I put <code>stop();</code> in every keyframe of the presentation. The problem is how to go back just to the previous keyframe (and I also want to go back in reverse playing). I thought it would be quite easy if I made a variable (called "zpet") and set it the specific number of frame where to go back in each keyframe. But it doesn't work, all the time it's going back to frame 1. For example I put in the frame 26 the code <code>zpet = 13;</code> that should say when playing back from the frame 26 stop at the frame 13. Any ideas how to solve this? I would be really grateful for that..</p>

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.
