Clipping shortcut doesn't work for me

Hi everyone! I’ve been using Omnifocus for many years now and I never felt the need to create a clipping shortcut to gather some web links, but, when yesterday I tried to do it, it never worked: every time I clicked on the dedicated button, OF Help comes up, as on the pictures below. I searched if any other app could use the same shortcut, in case there would be some conflict, but there is none. My OF version i : 2.12.2 (v113.41 r308135). So, how could I do it? Thanks for your help!
