@ -415,6 +415,8 @@ Some parameters provide a way to change the context of execution:
* +-itersel+ (requires +-draft+): execute once per selection, in a
context with only the considered selection. This permits to avoid
cases where the selections may get merged.
* +-buffer <names>+: execute in the context of each buffers in the
comma separated list <names>
The execution stops when the last key/command is reached, or an error
is raised.
