Is there any way of assigning keyboard shortcuts to the resizing of the Brushes? Having to move the mouse up to the tab on the tool bar and then either move the mouse to resize or type in a size is a major disruption to workflow. This is particularly annoying when you have found the spot or click you need to clean and you have zoomed in/out the brush is too big/small since it's size is not related to the zoom level in any way. The size numbers don't seem to have any relation to either pixels or audio time formats.
Ideally using the Up/Down keys when the Brush is selected to alter size would be good. Or alternatively being able to have preset sizes assigned to Keyboard shortcuts.
