Seeing GitHub Copilot Suggestions But You Can’t TAB to Complete Them?

It is obviously a matter of keybinding conflicts.

How to Fix

  • Just open keyboard shortcut preferences in VSCode.
  • Enter tab to find all keybinding related to tab.
  • Invest them and remove them one by one until GitHub Copilot tab completion works.

Please feel free to remove any of your keybinding settings, for they are not really removed, they are just overridden by user keybinding settings. You can always find them later by search @source:user in your keybinding settings and click Reset Keybinding to restore them.
