How can I open the breadcrumbs dropdown using only the keyboard in VS Code?

In VS Code, Is there a way to open up the file selector dropdown, i.e. this:

with just the keyboard- such that I will be able to use the arrow keys + enter to switch files?

You can use the following commands (in the command palette, or use the corresponding keybinding):

• Focus Breadcrumbs (On Windows and Linux, ctrl+shift+;. On macOS, use cmd instead of ctrl). You can then use the arrow keys and the enter and escape keys to navigate.

• Focus and Select Breadcrumbs (On Windows and Linux, ctrl+shift+.. On macOS, use cmd instead of ctrl). You can then use the arrow keys to navigate.
