I can now paste/type the SQL statement first, ALT+G, enter new SQL name, F5 to execute
1.Open a Query Editor window connected to your favorite server.
2.Right click on the Change Connection toolbar button on the Query Toolbar button and select the Customize command at the bottom of the menu.
3.Right click on Change Connection button again and then change the command name "C&hange Connection..." to "Chan&ge Connection...". This will change the hot key from Alt-H (which would conflict with the Help menu hot key) to Alt-G.
4.Finally, in the Right Click menu for the Change Connection button, you need to select the command option to display both "Image and Text". This exposes the Alt-G command to the Query Editor.
5.You can now close the Customize dialog and use Alt-G as your hot key!
