Here are the basic keyboard shortcuts in iOS 11

iOS 11 has some very useful keyboard shortcuts yet. They’re especially useful for iPad users. Here are the basic you should familiarize yourself with:

⌘ (Command) + H: Navigate to the home screen from anywhere.

⌘ + Tab: The quick app switching behavior you've come to know and love on macOS.

⌘ + Space: Open up Spotlight search. I frequently use this as an app launcher if I don't want to move my hands from the keyboard.

⌘ + Up/Down: Jump to the top or bottom of a website or other such supported scroll view, respectively.

⇧ + ⌘ + 3: Take a screenshot.

⇧ + ⌘ + 4: Take a screenshot and enter the editing UI.

⌘ + Option + D: Show and hide the dock.

⌘ + period: In certain supported applications, this kind of functions as an escape/cancel key.

When you are in any application you can hold down ⌘ (Command) to get a cheat sheet about what shortcut keys that app supports. You'll quickly find that most shortcuts are similar or identical to their macOS equivalent. Things like ⌘ + C for copy, ⌘ + V for paste and so on. Not all apps do a great job at supporting every expected shortcut key combination though.
