meta_dots on a & d keys, instructions adjusted for a smaller screen.

The multiple_type2roc is just a clunky script I made to enable me to calculate AUROCs for all of the blocks for a participant so you probably don't want that in the main repository, AD_Instructions is probably the most useful git.

Adding "| strcmp(KbName(keyCode),'esc')" to line 49 and line 98 didn't make the Escape key close the program so I never committed that change.
