Can't locate Solution Explorer in VS

For some reason I can not bring up Solution Explorer in Visual code (17.4 Build 2406, Mac)

Ctrl +Alt +L: does not work
Nothing in “View” (menu)

Visual Studio Code is not Visual Studio.
Try Ctrl+Shift+E instead.
EDIT: Close with Ctrl+B (In editor is is bold text but in Explorer pane (and other panes too actually) it closes it. You can Repeat the former shortcut to move focus from Explorer pane to editor.
The other panes follow the same idea, just change the key:

  • F: Find
  • G: GIT (I remove the distracting GIT icon from the bar and use this shortcut instead)
  • X: Extensions
  • D: Run/Debug
