On my keyboard there is a ¦ symbol: it's shown as the third character on a key with its position being on the bottom right of the key: I've been able to type it here by copying it to the clipboard from another web page.
But no combination of keys that I can think of allows the entry of the ¦ symbol from my keyboard. There are Ctrl, Fn, Win, Alt & AltGr keys on my keyboard. I'm not able to upload a photo of my keyboard as there's a 2mb limit on uploading images on this website.
There is no | symbol on my keyboard: also obtained from another web page.
PS Hannu answered my question. But I am not able to mark his/her answer as 'Accepted' due to this website not giving me the option. Perhaps, this is because I am a new user.
