There's this plugin [0] that will not allow you to navigate the file by smashing the keyboard. Essentially what the plugin does is disable the hjkl and the arrow keys for 1 second after you type one of said keys. There's also the extreme version of this plugin [1] which will disable the hjkl and other similar keys entirely.
