Hi,

A bit late but I have been rather busy recently.

The " Tilde" key is usually the shift option on the hash key, so you press shift+# to get ~

On some laptops it is, as Shay says, on the first key of the normal keyboard, that is, the line of keys below the function keys. Laptops vary, so it might be shift+ or Control+alt+ before you hit that key.

You might also have to think about your language version of Windows and the language setting of your keyboard. For example if I use a UK keyboard with US settings, or the other way round, some keys shift places.

Hope that helps.
