On Windows I just tap F6 to do the same thing as clicking into the address bar on Chrome, on Mac it does nothing even after I make the F keys "standard function keys" in keyboard settings, but nothing I do makes F6 on the Mac keyboard do the same thing as Command+L.
I've tried going into [Apple icon] > System Preferences > Keyboard > Shortcuts > App Shortcuts > + icon, then added Google Chrome.app and set "Jump to the address bar" as F6 (based on Google's Chrome shortcuts doc), but to no avail.

Under System Preferences > Keyboard > Shortcuts > App Shortcuts I added Google Chrome's Open Location… menu command, as shown in the image below. Note the ellipsis at the end has to be there!
