If you open DrRacket, a new tab opens with #lang racket. I can type anything I want, a lot of random characters, numbers etc. As soon as any keyword is recognized, there’s the pause. For example:
Hejheke Idhnehje Osjdjvehjekd Hdiisbsidhjd Gueojd jdbdbskbd jdjdb defino definii define <- pause here It does the same on any of my systems.
