Dill is the terminal-driver vane. You run your urbit in your Unix terminal, and Unix sends every event – such as a keystroke or a change in the dimensions of the terminal window – to be handled by Dill. Dill acts as an intermediary for anything that uses keyboard events, which results in a slight input lag in Urbit’s command-line interface.
A keyboard event's journey from Unix to Dojo, the Urbit shell, can be imagined as diagrammed below:
Keystroke in Unix -> Vere (virtual machine) -> Arvo -> Dill -> the Dojo
Dill is located at
/base/sys/vane/dill.hoon within Arvo.
