Keyboard shortcut to un/choose options

[schlomm]

Hello,
I don't know if this is the right place for an application question, and it may sound totally nooby-like, but:
What key-shortcut is needed to enable/disable certain options in a shell script, e.g. in the Proxmox VE LXC Updater script?
I'ved pressed every key, but nothing worked for me....

Can you post a screenshot or copy of the terminal interface? You should be able to navigate with the arrows, tabs, space and enter
