Jumping is easy; choose the entry that matches the base of the number you wish to jump, enter the number, and press the "Jump" button. The app will give you the number converted to the other three bases. There's no need to input common base prefixes like `0` and '0x` for octal and hexadecimal respectively.
Each keyboard for the entries provides buttons for: moving the cursor left and right, back and forward deletions, clearing the entry, and hiding the keyboard.
The app is limited to jumping numbers between 0 and 9,223,372,036,854,775,807. If a very large number within these bounds is to be jumped on a smaller screen size for the purposes of finding its binary representation, the arrow buttons will need to be used to scroll past the limits of the screen.
