Keyboard Shortcuts Do Not Work in Chrome 80

Pressing most short cut keys on the map does not work in chrome. For example there's supposedly a "token layer" or "map layer" and pressing ctrl-O tells the browser to open a file, it does not redirect to the webapp.

Nope sorry this doesn't work. I don't know what VTT is but when I click the grid / map and press CTRL-O for example, it just tries to open a file for the browser. This app doesn't work.

Hello and thanks for reaching out. I just gave this a try on Mac and Windows, and I found it to work. This might be a hole in our documentation. If you're on a Mac, the trigger key is Command (not Control). If this doesn't solve your issue, please let me know your Operating System you're using.
