I think I recall someone making a script back on Graalians a few years back which let players use the WASD keys on FB (with a,s,d keys for inven and grab rellocated elsewhere).
Not too sure where that thread is anymore tho. D:
And yea, the arrow keys are pretty terrible for a mouse user on Era. Although there isn't much of a chance that key binds would be developed to cater for the smaller amount of players who play Era on PC (like myself D
relative to mobile users.
So honestly, if it really provides such an inconvenience, I suggest switching to a mobile device to play Era
