Hello, could you kindly help?

In above link about flow action, it mentioned:

1. 

Short Descriptions

When you specify a description for the Short Description field, make the description meaningful in context to application users who must select one action from the list.

// here may I know where can I set Short Descriptions of a flow action? I can not find in the flow action setting form.

2. 

Action Section

On Perform user forms presented with the default action section ( Work-.pyActionArea ), the form area created by a flow action can offer the most likely action as the default, while allowing the user to choose other actions. The action with the highest likelihood appears as the default option on the left side of the section header. The section presents alternative actions in a click-action menu named Other Actions. The top of the menu displays connector flow actions, a horizontal line, and then local flow actions . Beneath the list of flow actions is a sub-menu called Add Work, which lets the user start a supporting process or add a child case — the choices depend upon your case management configuration.

// same, where can I find the form as above mentioned? At design or at run time?

Thanks.
