Switching between tabs

Sure you can do it but some of the fuction keys such as F1 have default actions setup already that are more useful (in Chrome F1 opens a new window). Just type this into the dev console and press F1, F2, & F3 to experiment

(function(){
  $(document).keydown(function(e){
    if (e.keyCode == 112){
      console.log(112)
      $("a[href=#tab_t1]")[0].click();
    } else if (e.keyCode == 113){
    console.log(113)
      $("a[href=#tab_t2]")[0].click();
    } else if (e.keyCode == 114){
      console.log(114)
      $("a[href=#tab_t3]")[0].click();
    } else {
      console.log(0)
    }
  });
})();

All the keycodes are listed in the link above.

Also remember that we are moving towards to voice commands and neural implants so you will just be able to speak the tab you want to move to ("Base Tab Three") or think of your tab and QuickBase will go there automatically.
