“⌘” is the key that the USB HID spec calls “GUI”. It is the same key as (for instance) “Meta” on Sun keyboards and the Windows logo on MS keyboards. Now you know how to press it. Your next problem is that much Linux software (Chrome included) insists on using the MS Windows convention of overloading Control for menu shortcuts. This is a great nuisance when you want to be able to use, for example, both Control-V (the conventional LNEXT character in *nix consoles) and GUI-V (the conventional Paste shortcut in GUIs). Pre-Linux X programs tended to get this right, since they were not focussed on slavishly imitating MS Windows. Apple got it right somewhat accidentally — the original Mac keyboard had no Control key at all, and it got added to support familiar editing and remote terminal uses.
