Yes I’ve got caught a couple times with that.
In regards to the original topic, I can definitely work quicker than I am able to change the parameters to what I need them to be at any given moment if that makes sense.
Definitely a ‘Ratio Reset’ hotkey, hotkeys for each Ratio extreme (full horizontal, full vertical, normal circle), and 4 ‘Size’ presets and 4 ‘Attenuation’ presets would speed things up considerably, this is where I feel a bit hindered whereas with these hotkeys I would be seamlessly flying through me eraser edits.

Even hotkeys that cue typing in the values into the parameters boxes might be good.
