The issue of "Housekeeping" has occupied YT Video commentators for years, and players too. Whilst I have made suggestions relating to picking up multiple goods at a time, in my opinion, there seems to be another factor to consider.
Mechanical keyboards may be harder to press
A possible alternative is a flat keyboard where minimal pressure is needed. When posting comments I use a tablet pc, and a stylus and only have minimal strain. So for an experiment, I am buying a flat keyboard for use with Stalkersoup, where I can use it with a desktop PC, and a stylus. Tapping keys thus, I hope will be be less risky for RSI and hence more enjoyable for playing Stalkersoup.
EDIT: Unfortunately, my tested board on wifi usb receiver ended in a Windows crash that took a few hours to fix. Still I think a finger rubber guard as clerks in banks use to count money will be my next atte,pt with a stylus inside it should allow striking of a conventional keyboard to avoid the rsi that has affected my index finger transferring bandages etc.
