The present disclosure is directed to methods and systems for processing replacements to a target array according to an ordered list. A system may provide automatic and intuitive identification of selectable tokens by iteratively identifying all selectable tokens for processing or replacement in an array, and, for each selectable token, determining a unique vector or angle to the selectable token from a predetermined position. The selectable tokens may be placed in a list ordered by the vector or angle. A user interface may indicate a candidate selectable token and allow the user to either select the token for processing or replacement, or navigate through the ordered list to a different candidate selectable token. In one such implementation, the user may modify the vector or angle, and the user interface may highlight another candidate selectable token corresponding to the modified vector or angle.
