When I want to edit the range of the quarry in the shape card I always try to use the tab key to quickly enter the new coordinates. Hitting that key however inserts a weird symbol and doesn't switch to the next input field. If this could be improved, it would be a lot of help. Also clarifying which axis corresponds to what input would remove confusion, since not everyone seems to keep to the x,y,z schema by default (e.g. Journeymap) or doesn't think of it that way.

This Issue seems to be present in Minecraft 1.9 in general. Im not sure but its maybe not RFTools related. Its a little bit anyoing indeed.
Btw meant "HT" above the usual line ?
