In R2012b on the toolstrip you can add items that you commonly use in the toolstrip to your quick access toolbar (QAT) - however not all items can be added
So as requested in another question here is a screen shot and a new question.
In the image (left) below you will see that when I right click on the Clear All, Set/Clear etc I get the right click option to add to the QAT.
When I click on the Stop on Errors and Stop on Warning I dont get the option.
Note: I know I can add it manually via my own shortcut - I was just wondering why some items can be added with right click and some cant....
