Is this possible?

From what I understand, Ctrl+Home is the function for resizing hotbars.

European laptops / keyboards do not have a "Home" button, and I cannot figure out if there is a European equivalent.

I have tried Ctrl+fn, Ctrl+window, ctrl+alt, ctral+altgr, control+fn+left arrow, to no avail.

Has anyone figured out how to do this?

Thanks!
