Command keys are special keys on a computer keyboard that perform specific functions or commands when pressed in combination with other keys. On Apple keyboards, the Command key (⌘) is widely used for shortcuts, such as copying (⌘C) or pasting (⌘V) text. In Windows keyboards, the equivalent is the Control key (Ctrl), which serves similar purposes. These keys enhance productivity by allowing users to execute commands quickly without navigating through menus.
The two keys that will toggle between active programs in Windows are "Alt" and "Tab." Pressing "Alt + Tab" allows you to cycle through open applications, enabling you to switch to the desired one easily. On macOS, the equivalent shortcut is "Command + Tab."

"Modifier" keys include Control and Alt on Windows / Linux computers, Command and Option keys on a Mac, and Shift and (in some rare cases) Fn keys on any of the above platforms. These keys are nearly always pressed in combination with other keys to change their purpose - such as the classic "Control-C / Control-V" for copy and paste. However, all of these keys can potentially be used on their own if a program is designed to watch for them - most often, this is found in gaming, where keys like Control or Shift can be used for a specific command like firing a weapon or running.
Goto. You can activate it by pressing the F5 keys.
There are people with limited use of their fingers who can't hold down more than one key at a time. This makes it hard for them to issue a Print (command-P) or New Document (command-N) command, or Cut (command-X), Copy (command-C) and Paste (command-V) things into place. Sticky Keys makes the computer think the modifier keys (shift, command, option, control, alt) are held down until you push the key they're modifying. So...if you want to do Print Setup in Acrobat (command-shift-P) you can push the command key, the shift key and the P one at a time rather than having to hold them all down at once.
