This feature is shown every time I press Alt key to quickly access the menu options.
However this slows down the menu option selection on the Ribbon tab.
On the V8i Select Edition, it is very smooth and quick to use Alt + Shortcut Letter (just underlined.)
Thank you for your posting. The method provided in the current STAAD.Pro was changed to suit the style that is now adopted by all ribbon based applications. We will look at the performance.
