recovery install osx- sign into apple id without mouse
Hello, I'm trying to install osx on my macbook in recovery mode without a mouse using a usb drive (my trackpad works, I just can't click with it). I was able to get so far as to select my usb drive to install to, but only by using voiceover. Afterward it opens a new window for me to log into my apple id which is where I have a problem. I'm able to navigate the install osx screen using commands, but the apple id window seems to be separate; I can't tab over to it and I can't access it with voiceover (in fact everything in the background shows the loading wheel). Anyone know a command that will allow me to switch over to the apple id log in window? I have tried cmd+tab, cmd+shift+tab, cmd+`,cmd+shift+` with no success. Please help!
