It all depends on your form, are you using the poke method? The proper way would be to put you're index fingers on f and j. Then middle fingers on d and k. The ring fingers should go on s and l. Pinkies should go on a and ;. The thumbs should go on space. Lets say you want to type "rewind" Bring your left index finger up to "r" then left middle finger up to "e" and the left ring finger up to "w". All your fingers should be moving only vertically, besides your index fingers which are used to type "t,y,g,h,b,v,n,r". Hope this helped! Practice makes perfect!
