How do you create a custom command, assign it an icon, and include it in the Quick Access Toolbar (QAT) in Excel (2010)?
As an example, [Ribbon > View > Show (section)] includes the option to show or hide (Row & Column) Headings.
I looked for that as an existing shortcut (to add to my QAT) by going to:
File > Options > Quick Access Toolbar > All Commands
However, although I looked under [Headings], [Hide Headings], [Show Headings], and [Unhide Headings], I could not find it.
Can someone explain how to create a custom QAT shortcut for that function?
