Oh. You can select different graphics options from the menu and change them while playing. So... Start out with a tile set then when you want to identify something go back to the ASCII graphics so you can type in the character you want to id. Then... Change it back to tileset graphics. I think they are trying to wean me into playing in ASCII gradually lol. It is kinda semi sorta working...
People have even written Angband comics (if you are into nerdy humor)
