USE and select POTION WITH CTRL or other KEYs

hi, i am new here. just installed hellgate london 2038. Man!!! it works flawlessly on win10 64bit
and just the with initial testing, i can see real improvements. keep up the good work, let me know where i can contribute some moola…
anyway, back to why i post this. i accidently remove the health potion from the crtl key shortcut
and i cannot find anyway to put it back, search this site provide no clue. so what do i have to do to put potion, either health or energy back in crtl, cant we use other keyboard shortcuts?

sorry to mention that i am playing single player only.
