Pressing characters one by one for Name Input can be slow and tedious. This plugin allows you to use the keyboard to perform name entry on the Name Input Processing Event. There, players will have full range of their keyboard to enter in character names. If they prefer the manual input, they can click the mouse or press arrow keys on the keyboard to immediately switch the name entry to manual letter entry as well.
