I'm running FGU on an apple and one of the key commands for helping me edit content isn't working. I'm manually entering in some races and classes, and I need to have tables in the class info. The key command ctrl+tab isn't working to add a new cell. Ctrl works with other keys for other commands, like copy and paste, and it works to quick command change the kinds of lines of text. Is this a bug, or am I doing something wrong?
