Short cut for resizing the magnet tool

[macnavi]

Being a Photoshop user, the magnet tool makes me pushing the brackets [ & ] to resize the magnet. But unfortunately, I don't see any short cut available for resizing. It would be great if the [ and ] would be allocated to the Magnet tool, so you can pull and push your object to shape quickly, without having to type in the number in the tool bar to change the size.

Should not be difficult to incorporate, right?

That info is on the status bar. Hold alt on the keyboard and drag the mouse to right or left.

Wasn't aware of this obvious fact, so thanks for that. Still I woul like to have those keys as short cut for the workflow. I prefer keys over mouse clicks.
