Do you guys have bad experiences if you use shortcut keys like F / J / K / L? For example, if you use the F key to display a full video on your laptop screen or use the T shortcut key one time only, it is okay but if you use more than twice times to use the shortcut key, like if you click F shortcut key more than twice times, it will automatically pop out search text box even you didn't click Ctrl + F key to search the text on the webpage.
