why only alt(copy),ctrl(extrude) that are on the left side of my keyboard work in rhino?
that is not the case on my pc.
tested, both side worked
From what I can test, both sides are working just fine on my installation.
What version of Rhino are you using?
What are the exact operations you are trying to perform?
And is it possible there could be something wrong with your keyboard?
Or perhaps an incorrect keyboard layout active in Windows?
yes i think its not rhino setting its about window i think… i tested if it word out of rhino and it doesnt
i figured . it was window keyboard layout setting. it was disabled
