The user should be able to jump to the next file in a file manager when hitting the tab key, after starting a rename (with F2 or double click). [I tried enabling this feature without success](https://github.com/AObuchow/Sample-Commander/commit/12893a2a3d6fba585a3448fb6aed702869279b59#diff-161bc451ab15c32f5dc0ba1016a04a58R198), maybe I made some small mistake :P
