Highlight a number + Ctrl + Scroll in Matlab editor - bug or feature?

I'm just curious about the background on the following feature I discovered yesterday in the Matlab editor:

Write a number in the Matlab editor. Highlight the number. Then press down Ctrl and use the scroll wheel on the mouse. It appears that the number is changing by +1 or -1 (depending on the direction of the scrolling), and that the entire code block is executed for every step.

I haven't found any documentation about this, and me and my colleagues have not agreed upon whether we think it is a bug or a feature... ? In some sense, it's improvising a for loop, but we can't really see how to use it efficiently.

It appears to be present in at least the 5 latest Matlab versions, and also on different platforms.

It's most likely a shortcut to this feature (R2013b).

Seems likely, thanks!

(I'm still curious about when you need an "increment value and run section"-function, but that's probably just me... :-) )

How would you disable this? I have the same behavior in the editor, and when I accidently use ctrl-wheel on the mouse to increase text size (which doesn't work in Matlab editor. it's just a habit of mine), it changes numbers ... this is certainly something I would like to disable. thanks
