Direction keys

Hello, love the app. But there is one deal breaker in it for me. The forward and back directional keys are great, but i need up and down ones too,just like a real keyboard. When i type and the wrong words are guessed, i need to go back to them to correct them, often on a different row, and i would love keys for that, as moving the cursor on my tab A by finger is almost impossible when i want to select the row just above the keyboard, know what i mean? 

If you could make it an option to have all four direction keys i would freak out... 

Cheers guys,

G.
