The Shortcut Keys preferences application lets you view and edit system-wide keyboard shortcuts.
The left Ctrl and Alt keys are swapped in helloSystem by default to make shortcuts feel welcoming to switchers coming from the Mac.
A shortcut is a key or key combination you can press to invoke a defined action on your computer. Shortcuts can be defined by applications (per-application shortcuts), or can affect the whole system (system-wide shortcuts).
The Shortcut Keys preferences application lets you view and edit system-wide keyboard shortcuts only, not per-application shortcuts. Some applications contain similar functionality inside the respective application to view and edit per-application keyboard shortcuts.
The ⌘ key
The ⌘ key, also known as Command, is the key left to the spacebar on helloSystem, unless you have configured your system differently.
Non-native software may refer to the Command key as “Ctrl”. This is a known cosmetic issue.
Open the Shortcut Keys preferences application to view the default system-wide shortcuts.
Notable default shortcuts include:
Press ⌘ + Space to search in the Menu (e.g., to launch applications or to execute commands in the frontmost application)
Press Ctrl + ⌘ + Esc and click on an application window to forcefully quit an application that is malfunctioning
