Cannot get upfront text editor to work

Hi

Upfront looks pretty interesting but I am having problems using it...
I am following the first tutorial on basics and it says that you can edit a text area...
how do you recognize a text area? I tried clicking on the menu bar to change the logo text but that is an image...

I tried dragging a text element onto the header area and i do add a text area containing my awesome stub content goes here... and double click to edit text... i am using a MS Surface Pro 3 with a surface keyboard and no amount of double clicking does anything.. not even tapping on the screen... please advise

finally... are there any decent youtube video for upload... I see the css hero but that is just onscreen how to without any words...

thanks

george
