I simply cannot ping

I'm a Roll20 newb, so the following is probably my own fault. During the tutorial, I reached Pinging practice. The instruction says to left-click. I cannot left-click on my macbook. I'm using Chrome. I've tried every button I have, but no ping. Any suggestions?

(Quick search on how to left click with a mac) Try pressing down on the trackpad to click. If you go to the trackpad system preferences, you can enable tap to click, so you don't have to physically depress the trackpad. You should also be able turn on secondary click as two-finger tap.
I tried that in the turorial without any luck. Hopefully this is will work better in-game. Thanks.

Sorry I could not be of more help as I'm a windows user.

Clicking the trackpad is left clicking. Make sure you're on the right tool (the arrow). You can't ping with the other tools.

Thumbs up on that question, Terry. I forgot the basics to ask sometimes and make assumptions
