Description:
tool to help developers improve keyboard accelerators
Alt_Key is an application that instantly shows where keyboard accelerators should go in menu option texts and dialog labels. It is very fast because it uses the Kuhn-Munkres algorithm, easily outperforming all the naive algorithms. . The program makes it straightforward for developers to find the right characters to use as accelerators for menu option texts and for dialog labels. This helps make GUI programs more usable by catering for users who can't use the mouse and for fast typists who don't want to use the mouse.
