User commands[1] or user-defined commands[2] are a way for a user to introduce new commands in addition to system commands.

The benefit of using user commands is that they can be executed without having to explicitly copy their code into the active workspace.[1]

APL user commands start with a right bracket, e.g., ]yourcommand.

In Dyalog APL, many useful user commands are included into the distribution, e.g., ]boxing on, ]plot, etc. Special command ] -? allows to see a full list of user commands.
