Obviously, this is different for everyone. For the common person, a setting of 135 to 150 works great. However, one should start with a value of at least 175, which is the default value. Then work down from there. The idea is to have the shortest time required to get the shifted state without having false positives.</p><p>Play with this value until things are perfect. Many find that all will work well at a given value, but one or two keys will still emit the shifted state on occasion. This is simply due to habit and holding some keys a little longer than others. Once you find this value, work on tapping your problem keys a little quicker than normal and you will be set.</p><divclass="tip custom-block"><pclass="custom-block-title">TIP</p><p>Auto Shift has three special keys that can help you get this value right very quick.
