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.
Corresponding source code (ctrl+f for "register2").
