Keyboard shortcut to focus the file list in Dolphin?

When using Dolphin, I often end up with focus on the "Places" left-panel. Moving keyboard focus to the main file list is a horrible process, involving pressing Tab *once per entry in the location breadcrumbs bar*. Is there any keyboard shortcut to move focus directly to the file panel? https://unix.stackexchange.com/questions/361177/how-to-switch-pane-in-dolphin-using-keyboard explains how to move keyboard focus *between* the left/right pane, using Tab. However Tab does not move focus from Places to the file pane.
