proceed is possible, and the response text (for example ‘OK’) is placed on the left
softkey.
The Selection key always causes the same action as the left softkey.

Guidelines for designing confirmation queries:
When designing the prompt text, make sure the ‘positive’ answer is also the safe
one. Users tend to proceed pressing the left softkey or Selection key without
thinking too much.

Use descriptive softkey labels whenever possible. For a query about deleting
something, it is better to label the softkeys as ‘Delete’ and ‘Keep’ than use
generic terms like ‘OK’ and ‘Cancel’ that are more complex to interpret.
Redundant confirmation queries should be avoided. Do not add a confirmation
query if there already are other forms of feedback, unless it is crucial that the
user gets a certain piece of information.
List query
A list query offers a list of predefined choices for the user. It can be used when more
than two options must be offered to the user. There is a prompt text (optional) on
top of the window, and a list of options to choose from.
The list in a list query is a menu list: the user can select an item or dismiss the query;
the Options menu is not available. The default softkey labels are OK on the left and
Cancel on the right - actual texts can be specific to the context. The Selection key
causes the same action as the left softkey.
Any list item layout suitable for menu lists can be used; see section List layouts.
