I'm not sure what is happening, but I want to fix it.
When you hold or press the TAB key the VERY first time it does not immediately trigger. If you continue to hold it, it triggers after about 1 second.
However, every time after that first tab, it then always triggers immediately as expected.
is this a bug or is Construct doing with an invisible address bar or something? I would expect either to not work at all or always work.
see example here. You have to run it FULLSCREEN or it freaks out on the address bar.
