If I type, it should type what I type.
Do not slow down my typing because you want to present a live search. I type 60 words/minute, except when I'm typing in a live search box, and then I'm down to 60 characters/minute plus a bit of hatred because a website wants to slowly update the live search after every character.
If I click, it should click what I click.
Do not redraw the screen beneath neath my cursor in-between the beginning of the click and the end of the click. I don't know how this even happens. I've already started clicking on a result on your live search, it shouldn't be updating as my click happens.
If I select text, it should select what I select
