At my day job I spend a mountain of my time in Google Spreadsheets.
Some of the navigational shortcuts that exist in spreadsheets I think could be highly useful in aseprite.
I know we already have hotkeys to navigate individual frames within the same tag, which is nice.
However having a set of hotkeys that would jump to previous or next Tag group would be great for documents with lots of tags in them as well as if those tags have lots of frames in them. (I secretly hate scroll bars.)
