I suspect this was raised before, in which case apologies for the duplicate post.
I want to open my TW in full screen mode when on mobile. The below action works fine upon clicking a button but it does not work as a startup action:
<$action-sendmessage $message="tm-full-screen"/>
Is this a current limitation of TW in that action messages cannot be invoked prior to launching all TW modules on startup? If it’s not then how could I make it work?
Thanks
Hi @hubertgk sadly this is a browser limitation. Going full screen can only be triggered from within a user interaction.
It’s to guard against attacks such as creating a webpage that immediately goes full screen and renders a fake Chrome user interface, with a fake address bar. If the user then types “facebook.com” the fake Chrome can put up a fake password dialogue and harvest the users password.
Thank you Jeremy for the detailed explanation. That’s absolutely fine and justified and something I wasn’t aware of.
I’ve added a full screen button onto my sidebar instead 
Best regards
In fact, it’s more convenient to add a fullscreen shortcut，like use alt f
Right. Though this thread never mentioned browser activation in KIOSK MODE. For some situations kiosk mode is an excellent full screen control experience.
Just a comment, TT
If you open your wiki in Chrome > click the ellipsis > add to home screen, it should open full-screen every time you click the shortcut (at least on Android).
