Apple TV Remote hidden controls

Question

Are these controls legit? While in know some of these are simple and work on the device without much risk, I don't want to blow my device trying out unknown/new control.
Restart Your Apple TV
p><span>This is my favorite tip on this list because I frequently find myself navigating into the Apple TV’s layered Settings screens to restart the device whenever it gets <a href="/glossary/wi-fi" title="Wi-Fi is a way of wirelessly connecting to the internet over a broadband connection." class="lexicon-term">Wi-Fi</a> issues. Well, no more! Simply press and hold the DOWN and MENU button at the same time for six seconds to restart your Apple TV.</span></p>
h3 dir="ltr"><strong>Sleep Your Apple TV</strong></h3>
p><span>You can also quickly put your Apple TV to sleep using the remote. Usually it goes to sleep at after a predetermined amount of time passes. To make that happen sooner hold the PLAY/PAUSE for five seconds.</span></p>
h3 dir="ltr"><strong>Get To Home Screen Instantly</strong></h3>
p><span>Sometimes you can be knee deep in submenus on the Apple TV, especially when using some third-party channels. The good news is you don’t need to back out of each sub-menu step by step. Simply press and hold the MENU button on the Apple TV remote for three seconds and you’ll be taken to the Home screen right away.</span></p>
h3 dir="ltr"><strong>Arrange / Hide Channels</strong></h3>
p><span>For the longest time the layout of the Home screen was fixed, but then in a software update last year Apple finally added the ability for the user to rearrange and hide channels. This no doubt came in response to the increased availability of third-party channels on the Apple TV--some of which a user may never have an interest in viewing.</span></p>
p>To rearrange channels simply hold down the SELECT button for two seconds. The channel icons will jiggle. Use the DIRECTION arrows to move the selected channel. Or press the PLAY/PAUSE button to hide an channel.</p>
h3 dir="ltr"><strong>Rewind / Fast Forward At Different Intervals</strong></h3>
p>Everyone knows you can use the left and right direction pad to skip backwards and forwards, but you can actually use the same left and right buttons on the direction pad to rewind and fast forward at different intervals. Hold the LEFT button to rewind 30 seconds. Press the LEFT button to rewind continuously. Alternate your rewind speeds further by pressing LEFT once each time to cycle through slow, medium, or fast rewind.</p>
p><span>The opposite applies to fast forwarding as well. Hold the RIGHT button to fast forward 30 seconds. Press the RIGHT button to fast forward continuously. Alternate your fast forward speeds further by pressing RIGHT once each time to cycle through slow, medium, or fast fast forward.</span></p>
h3 dir="ltr"><strong>Go Slow-Mo</strong></h3>
p><span>This one is really cool. You can rewind or fast forward through video in slow motion on the Apple TV. To do this simply press the PAUSE button then press the LEFT or RIGHT button to rewind or fast forward in slow motion.</span></p>
h3 dir="ltr"><strong>View Video Settings</strong></h3>
p><span>Sometimes you might want to adjust audio or other settings for a video that is already playing. You can use the Apple TV remote to quickly do this by pressing and holding the SELECT button for three seconds while the video is play. This will bring up the video’s settings including subtitles, speaker settings, audio, and closed captions.</span></p>
h3 dir="ltr"><strong>Mark Episodes As Watched</strong></h3>
p><span>Many times we have full TV series we’ve bought via the iTunes Store that we watch on the Apple TV. However most of the time we’ve already seen some of the episodes in each season. This tip allows you to use the Apple TV remote to mark episodes as already watched. To do this you need to be in the iTunes TV Shows channel on the Apple TV. Select the episode you want to mark as watched and then press and hold the SELECT button. You can also mark entire seasons as watched by selecting the season and then pressing and holding the SELECT button as well.</span></p>
h3 dir="ltr"><strong>Pair / Unpair Apple TV Remote</strong></h3>
p><span>If you’ve got lots of Apple TV’s in your house you may have some remote conflicts. The good thing is you can quickly pair and unpair remotes simply by using...the remote. To pair a remote to an Apple TV press and hold the RIGHT and MENU buttons for five seconds. To unpair a remote from an Apple TV press and hold the LEFT and MENU buttons for five seconds.</span></p>
h3 dir="ltr"><strong>Switch On-Screen Keyboards</strong></h3>
p><span>Using the on-screen keyboard is one of the chores of navigating the Apple TV. You’ll use this keyboard whenever you need to enter login information (say, for Netflix) or when you are searching for a show. Thankfully the Apple TV remote has these hidden controls to make using the keyboards easier.</span></p>
p><span>Press PLAY/PAUSE when entering text to switch between the alpha, numeric, and symbol keyboards. You can also hold down the SELECT button for two seconds to bring up the accented characters and then press PLAY/PAUSE to select the one you want.

Welcome to the Apple Community.
If you don't want to use a remote with your computer the easiest thing to do is just to turn the IR off. (System_Preferences/Security/General)
If you still want to use your computer remote then you must pair your computers remote with the computer AND the Apple TV remote with the Apple TV.
To pair a remote with a device hold down the menu and FF buttons together for six seconds or until you see a chain icon on screen (best take the computer into another room, or turn it off, when you do this)
