here have text tells user click enter continue. wondering how blit 1 index of string example blit
storyfont[1] , blit 'l' screen. did try , did not work. thank help.

as far know, can't edit pygame render instance. however, create variable contains normal string, render that. instance:

while not stop:         original_txt = 'click enter continue...'         text_to_be_displayed = original_txt[1]         gamedisplay.blit(map, (0,0))          storytext = pygame.font.sysfont("monospace",25)          storyfont = storytext.render(text_to_be_displayed,5,(red))         gamedisplay.blit(storyfont,(50,500)) 

hope helped.
