Tablet RCT6773W22B/RCA 7 Voyager II

So I bought a mouse and keyboard for my Tablet thinking that Minecraft Pocket Edition would be compatible Like PC. The issue is that for my keyboard the only keys that work are my arrow keys, and W, A, S, D, and ESC. E, Q, and etc wont work at all. And my Mouse cursor stays on my screen and the only way to move the screen with my mouse is to hold left click and then move my mouse around. Scroll wheel doesnt work at all. Right click still places blocks and when Im done aiming my mouse, if I left click for three seconds it will destroy blocks. Please Help
