Valve's Steam Deck is an impressive piece of gaming tech, but there's definitely a learning curve.
Even if you're familiar with the Steam store, and its TV-friendly "Big Picture Mode" that the Deck's SteamOS resembles, it still takes time to figure out how basic features from Steam on PC translate to the portable device's gamepad-style controls. It's easier than you might think at first, though.
Valve doesn't make it apparent up front, but Steam Deck users have a ton of button-based shortcuts they can lean on for help. All of those shortcuts involve holding the "Steam" button in tandem with one of the other buttons to produce different effects. Like I said, easy stuff.
The most important one to know just involves the Steam button. If you press and hold it at virtually any time, a whole list of all the available shortcuts pops up until you release the button. So for those times when you forget — like I have numerous times — you can refresh your memory painlessly, without having to turn to an internet search engine.
In terms of what I've used most, the Take Screenshot shortcut (Steam + R1) captures whatever is on your screen and loads it into an on-device library. If you want to then make your screenshots accessible on a computer (or some other device where you have Steam installed), you can easily send them to the cloud. Head to the Steam Deck's Media menu, highlight the screenshot you want to upload, press the Options button, and select Upload. That's it!
The virtual keyboard shortcut is also extremely useful for the many Steam Deck-supported games that require occasional typing. Just press Steam + X to summon a smartphone-style keyboard in a flash.
There's one catch, however. The virtual keyboard only works when Steam is actually running. In the standard SteamOS mode, that means you can call up the keyboard from virtually anywhere. But the feature is more limited if you're using the Windows-style "Desktop Mode." It still works in apps like Chrome, but you'll need to have the desktop version of Steam running in the background (there's an icon for it on the desktop). You probably won't use the feature too often in desktop, but it's useful for those times when you want to install non-Steam apps like Discord.
You can also tweak the screen brightness in an instant — which can help preserve battery life — by holding that Steam button and tilting the left thumbstick up or down to increase or decrease brightness, respectively.
The last big one to remember: Steam + B (long press), which is the Steam Deck equivalent of Force Quit on Mac and Alt + F4 on Windows. Games mess up from time to time, and Steam Deck won't always be able to fix it for you. It's easy enough to reboot by pressing and holding the Power button, but the Steam + B "Force Game Shutdown" command gives you another option. I've used it plenty.
Take the time to dig through the menus if you've been lucky enough to score a Steam Deck. There's a lot of not-so-visible features that are easy to miss if you're not looking for them.
