VBA Comment Shortcut
View > Toolbars > Customise (or right click on the tool bar and select Customise)
Under the Commands tab, select the Edit menu on the left.
Then approximately two thirds of the way down there's two icons, Comment Block and Uncomment Block.
Drag and drop these onto your toolbar and then you have easy access to highlight a block of code, and comment it out and uncomment with the click of a button!
