Normal caps lock location for me is remapped to Tab (via keyboard firmware), usually remap Tab to Esc. I use tab/shift tab all the time for moving text around so it is less reach for my pinky, I rarely use caps lock so I keep it on a layer instead of a high value location.
If I recall correctly the globe key brings up the emoji and symbols picker.
I realised why I didnāt recognise the icon as out of all the keyboards I have here, only my most recent one has the globe icon! All the others just have āfnā. Funny thing is I use it all the timeā¦ for emojis
