Frustrated, Steele took it upon himself to the solve the problem. He gathered together the four different macro packages and began assembling a chart documenting the most useful macro commands. In the course of implementing the design specified by the chart, Steele says he attracted Stallman's attention. "He started looking over my shoulder, asking me what I was doing," recalls Steele. For Steele, a soft-spoken hacker who interacted with Stallman infrequently, the memory still sticks out. Looking over another hacker's shoulder while he worked was a common activity at the AI Lab. Stallman, the TECO maintainer at the lab, deemed Steele's work "interesting" and quickly set off to complete it. "As I like to say, I did the first 0.001 percent of the implementation, and Stallman did the rest," says Steele with a laugh.
