I'm currently going through and tweaking the metadata of a bunch of individual records, which means I need you use the little next arrow. When I mouse over the arrow, I'm told that the keyboard shortcut is Alt + Right, which would be fine if I didn't have such tiny hands.

I can't easily hit both those keys on my keyboard with one hand. I'd like to be able to change the shortcut, but I'm not sure where I can do that. I went to the Keyboard menu under preferences, but this doesn't seem to be one of the options available for customization...
