10.4.1 Confirmation and Completion

Dangerous operations that may lead to data loss have to be confirmed by default. With a multi-section selection, this is done using questions that can be answered with "yes" or "no". When the region isn’t active, or if it doesn’t constitute a valid section selection, then such commands instead read a single item in the minibuffer. When the value of the current section is among the possible choices, then that is presented as default choice. To confirm the action on a single item, the user has to answer RET (instead of "yes"), and to abort, C-g (instead of "no"). But alternatively the user may also select another item, just like if the command had been invoked with no suitable section at point at all.
