All the docs keep referring to ⌃Space to launch IntelliSense so as to get suggestions for config files, launch configs etc. As I understand from this chart that translates to the key combination control-space.
However on Mac OS X 10.11 ⌃Space only opens Spotlight. How do I trigger VS Code InteliSense from the keyboard on a Mac?
^Space means Ctrl + Space, not Cmd + Space (which definitely triggers Spotlight).
You can customize keyboard shortcuts according to the doc.
