This feature is about executing a query at the cursor position. And that query can be a one line or multiline. I have assigned a play icon button and F5 as the keyboard shortcut for the Execute Query feature, and for Execute Script, Playlist icon button and Alt+F5(Others),Option+F5(Mac) as keyboard shortcut.
As now the query can run at cursor position, so for user convenience I am showing the current query just beside the Data Output toolbar. And on hover of the text, it will show the whole query as a tooltip. This query text will be available for both Execute Script and Execute Query.
