IT8 implements the Alt = Add Glossary Entry Hotkey using the Add Glossary Entry Dialog command. If we were to introduce a new parameter moveToTop indicating that you want the added entry to be moved to the top you could then tweak your Add Glossary Entry Hotkey as follows:{CopySelection}{Wrap}
{AddGlossaryEntryDialog}
input = "text"
moveToTop = "y"
{/AddGlossaryEntryDialog}{Wrap}
{NoSpacing}
The new 2020-10-15 build introduces the suggested change to enable creating Add Glossary Entry Hotkeys that move freshly added entries to the top.
