See "Expose". Activation keys are different on different laptops, so find the shortcuts under
System Preferences>Keyboard. On my laptop:

• F9 shows all windows
• F10 shows all windows for the active app
• F11 shows the desktop

Swapping Command ⌘ and Control

NOTE: If doing the other keys, do this last. You'll have to do it again on the virtual keyboard otherwise.

1. Go into System Preferences.

2. Go into Keyboard.

3. Click on "Modifier Keys…"

4. Click on the menu adjacent to "Command (⌘) Key".

5. This menu should show up. Just remap Control to Command ⌘, and vice versa.

Non- Command ⌘ / Control Keys

Quite frankly, a large number of apps already support the Windows keybindings, and Mission Control makes Control+Arrow a small nightmare. But, if you must, this is how you do it.

In Karabiner-Elements, as shown by Clemsam, these combos are what you should map various keys to:

Home (Pos1): fn+control+←

End: fn+control+→

Control+←: Option+←

Control+→: Option+→

The JSON to do that is the following:
