Kagi Assistant help document lists ⌃ + ? (macOS) as a valid keyboard shortcut for Show Keyboard Shortcuts. However, pressing ⌃ + ? does not appear to do anything while on kagi.com/assistant.
Observed on macOS 15.2 using Firefox and Brave browsers.
Pressing ⌃ + ? should display keyboard shortcuts, similar to the keyboard shortcuts displayed on kagi.com when ? is pressed.
