Checking this option enables single key "hot keys" that are in almost all cases the equivalent of pressing the respective combination keys for the commands. As an example, pressing "e" (or "E") will perform the same command as pressing the Alt+E combination, launching the editor. See the combination keys shown on the menus for single key assignments. What is sacrificed for this capability is the standard OS/2 container response of automatic scrolling to the first or next record that starts with that letter.
